• How to benchmark apache/nginx setup

  - by Saif Bechan

  I am planning to setup nginx as reverse proxy. I will have apache to deliver my dynamic content, and nginx will deliver the static content. My configuration i have now is just Apache with fastCGI. This gives me no configuration problems and runs great. After I have set up nginx I want to run some benchmarks to see if I really got some performance increases, else i will switch back. Does anyone know how I can benchmark this type of setup? Or maybe someone did this already and have some canned results, I will be glad to hear them.

• Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

  - by Tim Mahy

  we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

• .vob to h.264 MP4 Files - Worth The Effort?

  - by harper89

  When I was doing the converting to digital format a while back I chose .VOB due to no quality loss. However recently I have been informed of this h.264 compression method. Time is not an issue here, I don't mind waiting for conversions etc. I also understand that any sort of compression will reduce quality. To test I converted a 4GB .VOB to a .mp4 using h264 in handbrake and the quality loss was very very very hard to notice. From what I have understood through research Space = .mp4(h.264) Quality = .Vob Playback = Both equally supported? But these concerns have yet to be answered: My comparison was done on a computer monitor, would the quality loss be substantially noticable if I purchased a 50 inch TV in the future? Is this type of file highly supported? (I don't want to experience incompatible players) What other issues could a conversion of files such as this cause in the future?

• Any good PostgreSQL client for linux?

  - by senotrusov

  stackoverflow points me "belongs-on-serverfault" on this, so crossposting. I am frustrated of not having a good Linux GUI administration and development tool for PostgreSQL. pgAdmin III is buggy and unusable piece of... hmm, software, compared to Windows-only PostgreSQL Maestro and EMS PostgreSQL manager. phpPgaAmin does not looks promising. EMS PostgreSQL manager can work under Wine, but such setup have a number of issues. Requirements are: Table data editing and browsing for large tables (1M+), able to jump by FK or some master-slave editing, GUI filtering and so on. ER diagrams with in-place schema editing Schema editing and browsing with all useful GUI support Schema changes log to put into DB versioning (migrations script). Tabbed interface to be able to work with a number of tables and SQL queries at once. And so on. Any ideas?

• What are the consequences of giving an AD domain differing NetBIOS and DNS names?

  - by Newt

  In the past, when creating AD domains, I've used the common convention of using a sub-domain of the company's publicly registered domain name, e.g "corp.mycompany.com" or "int.mycompany.com". I've always accepted the default NetBIOS name when running DCPromo, for fear that creating a NetBIOS name that differs from the sub-domain may cause complications. I've recently been doing a bit of research on the consequences of providing an alternate NetBIOS name. The main reasons behind this are: The NetBIOS name isn't particularly descriptive or unique to the company Apparently generic NetBIOS names such as "CORP" or "INT" can cause issues when merging IT systems (although I've not had experience with this myself) Providing something "before the slash" that means more to users (less important) In looking at the possible downsides, the only one I can come up with is the disjointed namespace issue when configuring Exchange. Can anybody with more experience than I elaborate on my findings at all? Many thanks

• How do I know if my SSD Drive supports TRIM?

  - by Omar Shahine

  Windows 7 has support for the TRIM command which should help ensure that the performance of an SSD drive remains good through it's life. How can you tell if a given SSD drive supports TRIM? See here for a description of TRIM. Also the following from a Microsoft presentation: Microsoft implementation of “Trim” feature is supported in Windows 7 NTFS will send down delete notification to the device supporting “trim” File system operations: Format, Delete, Truncate, Compression OS internal processes: e.g., Snapshot, Volume Manager Three optimization opportunities for the device Enhancing device wear leveling by eliminating merge operation for all deleted data blocks Making early garbage collection possible for fast write Keeping device’s unused storage area as much as possible; more room for device wear leveling.

• Video acceleration problem with Windows 7 games and PPTX files

  - by Jordan 1GT

  I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on. I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I have a .pptx file which is doing strange things in normal view and I suspect it may be related to the same video acceleration problem.

• Natively boot Virtualbox Image

  - by isync

  I am faced with a Windows hardware/software problem left over from another person. It's on me to resolve. It's a mission critical setup. The situation is: I've got a physical server machine with: -Disk C:\ (one disk) containing a basic install of Windows Server 2008 R2, formerly Win Vista Pro, now gone. -Disk D:\ (software Raid) containing a VirtualBox disk image of a configured Windows Server 2008 R2 running SQL Server R2 among others. What shall I do now? Migrate all the stuff from the configured VM to the basic but natively installed C:\ Windows Server 2008 R2 (with the possibility of breaking stuff)? Or, Setting up the machine to "natively boot" the VM with the help of bcdedit.exe (something I've read about, what I've never done, what I don't know of if it works, if it hits performance, or if it is stable for production) For me, being old skool, I am in the process of de-virtualising everything (option 1). But I'd be happy if someone suggests I am ok to go down the "natively boot" route.

• Windows 7 Service Pack 1 Install Failing

  - by Cu Jimmy

  I am having real trouble updating one of my machines to Win7 Service Pack 1. Its an Asus P5K board with an X9650 Quad Core Extreme chip, which is a less common type of chip. Was wondering if anyone has had issues with this kind of kit or if it may just be the motherboard is a little gone. The error message I get back from Microsoft Update is WindowsUpdate_80091007 and WindowsUpdate_dt000 which are fairly generic errors. Tried installing with the sp1 file based installer and got nowhere. The actual installer crashes with an SP Installer has crashed Its a fresh install on a fully scrubbed drive (an Intel 120GB SSD).

• Why does a group policy not applied to the domain administrator account?

  - by Saariko

  I have a working policy on my entire domain. I just found out, when logging with the domain administrator, that this policy is not applied (EDIT: Running : gpresult shows that the GPO's are applied - but, this GPO is for Drive Mappings, and the actual drive mappings are NOT shown) The administrator account - does not have any login script on his profile tab. My GPO's are mainly small/atomic settings: single GPO to handle each settings: UAC, Firewall, printers. GPO status for the object is enabled That's an overview of the Drive Maps: Reading on MS support site, I checked the delegation tab, and it is marked as applied to domain and enterprise admins. Every user gets these policies correctly. The OU that is set is the root of the domain. (for testing purpose - I did that to eliminate hierarchy issues - did not help) Block Inheritance is disabled. (never used it anyway) GPO link GPO Security Filterings

  - by Kuroro

  I am going to install a new SQL server 2008 instance on my development/testing machine. My machine have one 7200rpm 500GB SATA Disk (C:OS) and one Intel X25-G2 80GB SSD(D:). Details machine config is as follow: CPU:i7 860 RAM:8GB Microsoft said I have an option to place following directories in different disk. So I plan to place User database & Temp DB on SSD and rest of it on traditional disk. Is it a good choice for gaining a performance boost in fast SSD?

• Virtual machine won't connect to networking interface

  - by Keyo

  I have moved my virtual box hard drive (.vdi file) from windows7 on a laptop, to windows7 on a desktop. No big deal I thought. The OS is ubuntu 10.10. Now networking is broken. I don't have a solid understanding of windows networking, maybe someone can help. Anyway, the networking no longer works. I've tried to setup eth0. I have virtualbox setup in bridge mode, my wifi connection on windows to an intel card on the virtualbox side. I think it might be something to do with windows not allowing the connection to bridge properly (security issues). I've provided some screenshots, which will hopefully help.

• Offloading Cable Modem operations to Router

  - by Matt

  I may be crazy here, but I seem to recall a conversation in the past stating that it was possible to offload some of the operations taken by one's cable modem to one's router. The logic was that since the cable modem is often equipped with a cheaper processor as it is supplied by your provider, that it often chokes even crashes when you start a torrent or something else with a lot of connections. I seem to recall that some routers offered the ability to take some of the modem's operations. Is this possible or have I imagined the whole thing? I ask because my modem seems to have many issues when I start torrents.

• Create bootable partition from image

  - by Carson Darling

  I have a Macbook Pro with a dead CD drive. I don't have easy access to a replacement drive. I'm trying to install Ubuntu, and I can't get the MBP to recognize a USB stick as a bootable media (I believe MBP's have issues with booting from USB in some cases). Is it possible to take a disk image and write it to a partition on the HDD so that I can then boot from that partition and then install the OS onto a third partition? Partition layout: 150GB OS X 50GB Ubuntu destination 5GB Ubuntu install image

• Will more memory help my CPU-peaking SQL Server 2008 R2

  - by Tor Haugen

  I'm supporting a system running against a SQL Server 2008 R2. The server is a single-CPU box with 8 GB of memory. As traffic has increased, the server has started saturating, peaking to 100% CPU ever more often. Disk I/O remains moderate (somewhat surprisingly). Obviously, a new server would be the best option. But failing that, can I expect a noticable improvement from installing more RAM? Or does RAM only help for I/O issues (through caching)?

• Turning off Chrome's visual effects

  - by Wesley

  Is there any way to turn off the visual effects used by Google Chrome? For example, the tabs slide around smoothly, the scrolling is really smooth, and there is a huge arrow that fades in and out during download. Reason why I'd like to know is primarily because I want to maximize battery life on my netbook by using less visual effects and, secondly, because I use Chrome on slower systems and would like to maximize the performance and efficiency of Chrome. This applies mainly to Windows XP, but also Vista, 7 and even (X)Ubuntu 9.10. EDIT1: Oh yes... disabling the attaching/detaching of tabs and turning them into translucent in the process. That's a bit stressful on my slower machines.

• video streaming infrastructure advice

  - by Alchemical

  We would like to set-up a live video-chat web site and are looking for basic recomendations for software and hardware set-up. Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

• 10,000 RPM HDD (WD VelociRaptor) vs SSD for OS?

  - by GiH

  I currently have a 10,00RPM 150GB Raptor that I use for Vista. I'm about to upgrade to Windows 7, and while doing that I thought I'd buy another drive and install Ubuntu 9.10 on it. I don't want to partition the current drive I have, but I don't need 150GB for another OS. So, I'm having trouble deciding whether its worth it to buy a 64 GB SSD at the same price point as the 150GB WD VelociRaptor? Or should I just get a 7,200 RPM drive for really cheap (around $50)? Would it be better to use an SSD for the OS than a mechanical drive? I could always get a 32GB SSD too... Oh, and I don't want to virtualize Ubuntu because I'm going to be testing to see the differences in networking and overall performance.

• What's the downsides of Running Ubuntu 9.10 32bit on AMD64 Processor

  - by Omar Dolaimy

  Hi, I was thinking about installing Ubuntu 9.10 32bit on a DELL Inspiron 1501 with 64bit processor Laptop. Since It's was real pain to me to run Java Browser plugin, Flash Plugin, J2ME Toolkit, and many other tools. But It was 90% OK with me. This was Ubuntu 8.10 (a year ago), And now the Ubuntu 9.10 came and I'm thinking about installing the 32 bit on it and get rid of the pain. Is there a downside for that?? considering that the display card is not supported now so exclude this from your calculation, I will never play REAL games on it and I'm not a big fan of Compiz effects. I'm not here to ask about the performance (which is about 15%+ for the 64bit only), I just want compatibility!

• Why do browsers have so many possible exploits?

  - by Beau Martínez

  When browsing I am ocassionally given warnings about pages that host malware "that could damage my computer". I am seriously perplexed as to why, in 2010, browsers still have possible exploits and can be cracked. My question is "Why?". I'm assuming it's because of the quick development that occured in the browser wars which were unsufficiently tested, but I'm unsure. Surely WebKit would have patched all the issues in KHTML, or Gecko sorted out the flaws in Netscape's engine, and the IE coders sorted through their codebase to eliminate possible flaws? (Somewhat related: http://superuser.com/questions/117770/which-browser-is-the-most-secure-research-and-practically-based.)

• Proper way for changing MAC address in a linux VM?

  - by HappyDeveloper

  I tried to change the MAC address in a ubuntu VM (virtualbox), but after that it threw lots of errors during boot, and then I had no internet connection. Then I saw that the interface was renamed to eth1, so I edited /etc/network/interfaces to change eth0 to eth1, rebooted (didn't know how to restart the network), and boot was now faster and internet worked fine. But now after every time I log in, I get 1 or 2 error messages that say nothing, they only ask me if I want to report them. So I was wondering, is there was a proper way to change MAC address, to avoid these issues?

• External hard drive encryption

  - by Kragen

  I've got a complete backup of my main PC on 1.5 TB external hard drive that I carry around with my laptop so I can have access to all of my files while I'm on the move, however it has just dawned on me that if someone nicks my external hard drive they now have access to everything! Hence I'm looking for a way to encrypt my external hard drive. I'm after something that is: Secure (if I need to carry around a USB dongle to keep the key on so be it) Fast (the performance of the drive should still be reasonable) Cross-platform (I regularly use other peoples computers - Sometimes they are not windows based and might not even have internet access, however I still want to be able to access my files) Cheap (preferably free / open source!)

• NTFS disk mounted as fuseblk in ubuntu 12.10 is very slow and a lot of errors when rsync. Is that not a rare thing?

  - by Pablo Marin-Garcia

  I am having problems with a NTFS disk mounted as a fuseblk in my ubuntu 12.10 through external usb3. When I did a 1.1TB backup with rsync the speed was 1-2MB/s (wiht a ext4 disk speed was 70 MB/s before and after trying the NTFS disk). Also after one hour errors started to appear: rsync: write failed on "xxx": No such file or directory recv_files: "yyy" is a directory #but this file is a FILE not a dir ??!! .... As this is the first time I have mounted the NTFS in linux for heavy usage (the data would be used in windows afterwards), I would like to know if this kind of thinks are common o was only that something became unstable in my system and a simply restart would probably have solved it. This leads me to the these questions: Can I trust fuse for manage NTFS disks? Or is a problem of the NTFS tools in linux not yet totally stables for writing? Do people is still suffering from low performance with fuse-NTFS vs ext4 (in the past I have read about people complaining about this)?
