• Minimize writes to SSD disks with Windows 7

  - by mark

  Most people use their SSD as their primary system installation disk with Windows 7. W7 already has a lot of optimizations for SSDs, both in terms of performance and lifetime. Minimizing writes increases the lifetime of SSDs, so post each suggestion as an answer and let others vote on them. Update: I'm not sure anymore that minimizing writes is a good thing [tm], hard facts that SSDs will degrade within a noticeable time are missing and it seems this it can create a bit FUD about the functionality of the SSD. In other words: I question the usefulness of my wiki question.

• How to setup a daily report of the top e-mail senders in Exchange 2010

  - by Belmin

  We have had issues with compromised Exchange accounts sending a large amount of unsolicited e-mails out. We have mitigated this by using a cloud e-mail gateway that does a better job in detecting these outgoing messages as to not hurt our e-mail reputation. However, we would still like to detect any abnormal e-mail activities. One idea is a report of the Exchange accounts with the most outgoing message. Any idea on how to do this? Or a similar stat that may be indicative of an account being compromised?

• JBoss 4.2.3 Won't Start

  - by Thody

  Hi, I'm trying to start a new installation of JBoss 4.2.3, and it's getting as far as "INFO [Server] Core system initialized", then hanging for several minutes. There is a Java process running, but only at ~35%. Also, looking at the boot.log, there are no entries after ~1s after starting the boot. Any ideas what might be up? Update: After about 10 minutes, I got a handful of garbage collection warnings: GC Warning: Repeated allocation of very large block (appr. size 512000): May lead to memory leak and poor performance.

• ZFS on top of iSCSI

  - by Solipsism

  I'm planning on building out a file server using ZFS and BSD, and I was hoping to make it more expandable by attaching drives stored in other machines in the same rack via iSCSI (e.g., one machine is running ZFS, and others have iSCSI targets available to be connected to by the ZFS box and added to zpools). Looking for other people who have tried this has pretty much lead me to resources about exposing iSCSI shares on top of ZFS, but nothing about the reverse. Primarily I have the following questions: Is iSCSI over gigabit ethernet fast enough for this purpose, or would I have to switch to 10GbE to get decent performance? What would happen when one of the machines running iSCSI targets disconnects from the network? Is there a better way to do this that I just am not clever enough to have realized? Thanks for any help.

• Stream tar.gz file from FTP server

  - by linker

  Here is the situation: I have a tar.gz file on a FTP server which can contain an arbitrary number of files. Now what I'm trying to accomplish is have this file streamed and uploaded to HDFS through a Hadoop job. The fact that it's Hadoop is not important, in the end what I need to do is write some shell script that would take this file form ftp with wget and write the output to a stream. The reason why I really need to use streams is that there will be a large number of these files, and each file will be huge. It's fairly easy to do if I have a gzipped file and I'm doing something like this: wget -O - "ftp://${user}:${pass}@${host}/$file" | zcat But I'm not even sure if this is possible for a tar.gz file, especially since there are mutliple files in the archive. I'm a bit confused on what direction to take for this, any help would be greatly appreciated.

• An international mobile app - Should I set up EC2 instances in multiple regions?

  - by ashiina

  I am currently trying to launch an mobile app for users around the world. It is not a spectacular launch which will get millions of users in weeks - just another individual developer releasing an app. I know enough about the techniques of managing timezones, internationalizing string, and what not ( the application layer ). But I cannot find any information on how I should manage my EC2 instances... Should I be setting up EC2 instances in different regions around the world? Is that a must-do, or is it an overkill? I'm aware that it's the ideal solution in terms of performance, but it becomes very tough managing servers in multiple regions. DB issues, AMI management, etc... I'd much rather NOT do so. So I would like to know the general best practice when launching an international app/website. Note: For static contents, I know it's better to use a CDN, so I'm planning on doing so.

• Web Server Setup

  - by gustyaquino

  Hello, In my workplace, we want to implement your own web server for at leat 100 Apache/PHP/MySQL web pages. My boss is opposed to hiring skilled personnel, he think we can do ourselves. Currently, we are working with hostgator reseller account. I chose CentOS as the operating system, but I don't know the best hardware solution. HP, Dell ? What about the setup on these platforms? Thanks. PS: sorry for my bad english Edit: The purpose of this migration isn't related to performance issues. But independence.

• Recommendations for SSD for server and database use?

  - by Tony_Henrich

  SSDs are a new technology and they are constantly improving. A lot of the posts here were posted in 2009 when SSDs where less mature and not as fast. What was recommend back then is probably out of date today because of better options. The SSD is used to hold SQL Server databases. Size is probably 128G. The database is used with a CMS and web server so web pages need to get their data and render as fast as possible. Which modern SSD is recommended for such a use? Is there an SSD better than Intel X-25 E/M in terms of performance/cost? (I am also evaluating cost between : RAM + UPS (semi persistent) vs SSD for same amount of gigabytes. No RAID is involved)

• SSL on Apache seems to significantly affect WebDAV performace

  - by takesides

  I'm using Apache 2.2 running on Windows Server 2008 R2 as a WebDAV server for clients to upload large media files (roughly 100-2000MB). I am finding that when I have SSL enabled (openSSL 0.9.8o) and use HTTPS for the uploads the throughput is around 13Mbps but when I disable it and just use HTTP I get around 80Mbps. I can't understand why this is happening as my understanding was that the heavy SSL work was done at the beginning of the connection. Does anyone have any idea why the performance is so drastically affected by enabling SSL? Cheers.

• Are Virtual-Desktop Managers good or bad for system resources?

  - by jasondavis

  I am looking at Virtual-Desktop Managers for Windows 7. Right now it seems that VirtualWin is supposed to be about the best one available for use on Windows. I have never used anything like this though and I am just curious from others experience and knowledge, does something like this hog up a lot of system resources? I do not NEED it but it is a nice feature to have when I do want to use it, my PC's performance is more important then using it. So is virtual esktop managers a resource hog or probably not? Please share any tips/advice/ or comments on them, thank you =)

• Converting massive images to PDF, without crashing applications

  - by BloodyIron

  I'm trying to work with a large-format scanner, and we are scanning very long documents. Example, one of our documents we cut into two pieces, and one of those pieces is 3633x82486 in resolution. My application, Scanning Master 21+, which comes with the device (Graphtec CSX300-09) can output PDF, however when I try to save to PDF it complains about file being too large. I can successfully output to BMP however. GIMP can even open this BMP, after taking a while to load it. The resulting files range from 200MB - 1.2GB in size. Acrobat refuses to open the BMP format, saying it isn't supported or is damaged (which I know is not true). As I mentioned, the PDF plugin for GIMP crashes when I try to export to PDF. I'm really not sure what is the best tool for this job. So what is the best tool to produce PDF documents of very large images?

• Good TN3270 for MacOS? (Mac OS X Snow Leopard)

  - by Bbrado

  I need a good TN3270 emulator for the Mac that supports file transfers to TSO/ISPF (IND$FILE) and 132 char wide screens. Min 132x27 (3278-model-5), better even user defined size like 132x43. So far I've tried TN3270 (no file transfer) and X3270. Besides being an X11 app, unfortunately x3270 does not handle oversize screens correctly and Mocha only has a TN5250. So, what's the TN3270 of choice on the Mac (or how at least do I get x3270 to handle 132xSomething in ISPF correctly, e.g. SDSF Job-Class list)?

• ionice idle is ignored

  - by Ferran Basora

  I have been testing the ionice command for a while and the idle (3) mode seems to be ignored in most cases. My test is to run both command at the same time: du <big folder> ionice -c 3 du <another big folder> If I check both process in iotop I see no difference in the percentage of io utilization for each process. To provide more information about the CFQ scheduler I'm using a 3.5.0 linux kernel. I started doing this test because I'm experimenting a system lag each time a daily cron job updatedb.mlocate is executed in my Ubuntu 12.10 machine. If you check the /etc/cron.daily/mlocate file you realize that the command is executed like: /usr/bin/ionice -c3 /usr/bin/updatedb.mlocate Also, the funny thing is that whenever my system for some reason starts using swap memory, the updatedb.mlocate io process is been scheduled faster than kswapd0 process, and then my system gets stuck. Some suggestion? References: http://ubuntuforums.org/showthread.php?t=1243951&page=2 https://bugs.launchpad.net/ubuntu/+source/findutils/+bug/332790

• ESXI 4.0 Slow response in opening anything accross the network on a Virtual Server running Win2008

  - by user40944

  Hi I recently installed a HP ML350G6 Server with Windows Small Business Server 200864bit, Exchange 2007. The server was running fantastically and we transferred all user data onto the new server and no problems for 2 weeks! We then installed SQL2008 and transferred the accounts package onto the server and this is where the problems started. Users are now complaining to open a work document can take 2 minutes and the same with regard to anything else. The server itself seems fine, the virtual server seems fine! No disk performance problems (doesn't go above 50% unless i really copy lots of things), no memory, (12Gb only using 7Gb) cpu (usage is low average about 15%) etc on both the VM and in Windows Task manager. I have made sure disk caching is enabled on the raid controller (which made no difference). Network cards are running 1Gb and plugged into HP GB switch. Please help!

• Can NFS be forced to refresh stale files/directories when not using noac on the mount?

  - by johnnycrash

  We mount without using noac. I have a file that I append to once every 20 minutes. Then it will be read with mmap about 5,000 times a minute. We only mmap a couple blocks for each read. Needless to say, noac just kills the access performance, so we don't use it. I add data to the end of the file using a mount with noac and read from a mount without noac. The mounts that are reading are not seeing the new data. I want to know if there is a function I can call from c to refresh the attributes of a path and all its files. EDIT: I should add we cannot mount and unmount since there are 16 servers running on each system and they are constantly accessing the files. Well...maybe we could mount and unmount if each server used their own mount. I'd like to avoid that if possible. thanks!

• Making Windows 7 default to "All Files" when opening a document?

  - by krebshack

  I'm taking over an old coworkers job and part of that means I'll be working on various IFS tickets without any real ERP experience. I'm working with one user who is trying to check in documents in IFS. Right now, IFS defaults to JPEGs and then she has to select "All Files" in order find PDFs. Example: http://i.imgur.com/xK0iAfF.png As much as I'd like to say "it's one extra step, come on" the user's manager has insisted it interrupts her workflow and asked us to get on it. I've spoken with our IFS experts and they're unaware of any setting that would make the open dialog default to All Files in IFS. I've searched in Google for any setting in Windows 7 that would do that - but those have been unsuccessful - I keep getting results about changing which program opens a specific file type.

• After moving our Servers to a virtual environment using VMware - SQL timeouts came in, why?

  - by RayofCommand

  We moved our servers to a virtual cloud (VMware) where only our servers are in. But as soon as we finished migrating everything we are fighting against SQL Timeouts and machine slowdowns we can't explain. Even though we ~ doubled the servers capacity while switching from physical to virtual. Now I googled and found that we are not alone. People are complaining about poor performance after moving to a cloud managed by VMware. Are there any known issues? Sometimes our services can't access a disk or SQL receives a timeout and we have no idea why.

• How to monitor nginx proxy cache?

  - by Isaac

  I would like to see which objects get cached by my nginx reverse proxy (with an apache as a backend). So far I could not find a way, only the info that its not implemented yet. The reason is that I would like to tweak my configuration for best performance without putting too much stress on the server, as the backend is a production system. I know benchmarking would be better, but its not an option right now. So I though an alternative measure would be to monitor the cache. Is that possible, and if yes, how? (despite patching nginx with the patch mentioned in the link above)

• How to select the page range to print in Windows 8 Modern UI apps?

  - by Magnetic_dud

  Today I wanted to print an email from the Mail app (modern UI). I selected devices from the charms bar, and I chose my printer. The problem is that it was a very long email (a 40 replies unthreaded email), and I only needed the first page. It looks like there is no way to select a page range in the simple printing dialog, am I right? I solved the problem by inserting just one page in the printer and then deleting the job, but this is not a real fix... (I could print to a PDF printer, then open in Acrobat and print again, but...)

• Sharing RAM resources between 2 or more computers

  - by davee44

  I know there was a somewhat similar question before: How to share CPU or RAM? But, let me just specify it a little more... When Microsoft Windows requires more RAM capacity than available it uses a swap-file to temporarily store the data there, this is actually something like a hard-drive-based RAM. This technology is used for many years. Theoretically, it shouldn't be too hard to implement a similar technology that uses the RAM of different computer(s) in the network for temporary data storage. This just requires a software that runs on computers in the network that accepts and returns data from/to the main computer and keep that data in the RAM; plus the operation system of the main computer must have the ability to use computers in the network instead of (or in addition to) the swap-file. I wonder, are there any implementations of this idea? This would allow users to build RAM clusters using all of their home or office computers, that will boost the performance of a single computer for some development/gaming/video tasks, etc.

• Can not start Apache 2.2.22 in Fedora 15

  - by Roderik

  I am trying to start Apache 2.2.22 under Fedora 15 on my local machine. After fixing some errors related to missing modules, httpd -t will just give me 'Syntax OK'. However when I try to start apache as the root user: service httpd start it still returns: Starting httpd (via systemctl): Job failed. See system logs and 'systemctl status' for details. [FAILED] When entering systemctl I don't see any extra information other than: httpd.service loaded failed failed LSB: start and stop Apache HTTP Server So I wonder where to look now to get this back up and running.

• Setting CPU cores off-limits to all threads not specified (preferably in Windows 7)

  - by Shinrai

  I have a really specific machine configuration in the works that would really be helped out if there were any way to do this...basically what I'm looking for is the opposite of setting CPU Affinity for a process. I want to be able to tell Windows "No applications except [x] are allowed on [these cores]." Is there any mechanism whatsoever for doing this? (Yes, I am aware of some of the potential issues this could cause and I normally would never fool with processor affinities, since the OS usually does a damned good job itself, but this is a pretty odd situation involving some software that is very CPU-bound constantly having to wait on interrupts and DPCs and things from other threads.)

• sql server: losing identity column on export/import

  - by Y.G.J

  Recently I started dealing with SQL Server, my previous experience was in MS-Access. When I'm doing an import/export of a db, from the server to my computer or even in the server, all column with primary key loose the key. Identity is set to false and even bit is not set to the default. How can I can I use an import/export job to make an exact copy of the db and its data? I don't want to have to perform a backup and restore every time I want the same db somewhere else, for another project, etc. I have read about "edit mapping" and the checkbox but that did not helped with the identity specification... and what about the primary key of the tables and the rest of the things?

• what are the rules for SLI ( GTX 550 Ti )

  - by equivalent8

  I got ASUS GTX 550 Ti and I want to SLI it with another graphic card. I heard that not all graphic cards are good idea to SLI, (or not all combinations) because sometimes the final performance could be even worse that with one graphic card. Is that true? What are the rules ? ( maybe chip-set needs to be same or something ? ) I was wondering if you can recommend me what Graphic card should I use as with mine. Should I use same one (GTX 550 Ti) ?

• Solaris 10: Identify a PID and the CPU it's running on

  - by Marcus

  I have multiple instances of a database running on a Solaris system. I'd like to prove that each database process is being handled by a different CPU. Essentially, I want to be able to do something like a ps -ef | grep <process_name> to get the PIDs and then run another command (if required) to identify the CPU... Is prstat able to do this? I'm making an assumption that as each database instance is started each one uses a different CPU. I'm not sure if I'm understanding this correctly... The reason I want to do this is because Sun hardware has slow CPU's, but lots of them. Therefore, to get the best performance out of it, I need to try and spread the load among CPU's... Thanks
