  • RAID Array performance on an HP Proliant ML350 G5 Smart Array E200i

    - by Nate Pinchot
    We have a client who is complaining about performance of an application which utilizes an MS SQL database. They do not believe the performance issues are the fault of the application itself. The Smart Array E200i RAID controller has 128MB cache and we have the cache set to 75% read/25% write. The disk array set to enable write caching. Recently we ran a disk performance test using SQLIO based on this guide. We used a 10 GB file for the test found that the average sequential read rate was ~60 MB/sec (megabytes/sec) and the average random read rate was ~30 MB/sec. Are these numbers on par for what the server should be performing? Better than on par? Horrible? Amazing?

  • please explain my fio results - is O_SYNC|O_DIRECT misbehaving on linux?

    - by Zoltan
    I'm going mad over figuring out what the problem could be with one of our storage boxes. With a simple fio script I'm testing random writes using bs=1M and direct=1. The SSD is a Samsung 840pro attached to an LSI HBA (3Gbit/s ports). This is the result I'm getting under FreeBSD 9.1: WRITE: io=13169MB, aggrb=224743KB/s, minb=224743KB/s, maxb=224743KB/s, mint=60002msec, maxt=60002msec This is regardless of sync being set to 0 or 1. On linux, this is the result with sync=0: WRITE: io=14828MB, aggrb=253060KB/s, minb=253060KB/s, maxb=253060KB/s, mint=60001msec, maxt=60001msec and with sync=1: WRITE: io=6360.0MB, aggrb=108542KB/s, minb=108542KB/s, maxb=108542KB/s, mint=60001msec, maxt=60001msec My understanding is that since I'm operating on the raw block device, O_SYNC should not make any difference - there's no filesystem, any barrier, anything between the writes and the drive itself. Especially with O_DIRECT|O_SYNC set. Any ideas? For reference, here's the fio script I'm testing with: [global] bs=1M ioengine=sync iodepth=4 size=16g direct=1 runtime=60 filename=/dev/sdh sync=1 [rand-write] rw=randwrite stonewall

  • Using GameKit to transfer CoreData data between iPhones, via NSDictionary

    - by OscarTheGrouch
    I have an application where I would like to exchange information, managed via Core Data, between two iPhones. First turning the Core Data object to an NSDictionary (something very simple that gets turned into NSData to be transferred). My CoreData has 3 string attributes, 2 image attributes that are transformables. I have looked through the NSDictionary API but have not had any luck with it, creating or adding the CoreData information to it. Any help or sample code regarding this would be greatly appreciated.

  • 'if' block in IL

    - by Luke Schafer
    I think I might be missing something important, but I can't seem to figure out how to construct a conditional statement in IL with dynamic method. I've only dabbled lightly in it before, but I need to extend some code now. Is there some documentation somewhere that I haven't found (apart from the CLI documentation), or does someone have some sample code? That would be fantastic. Cheers,

  • Why does Django's dev server use port 8000 by default?

    - by kojiro
    (My question isn't really about Django. It's about alternative http ports. I just happen to know Django is a relatively famous application that uses 8000 by default, so it's illustrative.) I have a dev server in the wild that we occasionally need to run multiple httpd services on on different ports. When I needed to stand a third service up and we were already using ports 80 and 8080, I discovered our security team has locked port 8000 access from the Internet. I recognize that port 80 is the standard http port, and 8080 is commonly http_alt, but I'd like to make the case to our security team to open 8000 as well. In order to make that case, I hope the answer to this question can provide me with a reasonable argument for using port 8000 over 8080 in some case. Or was it just a random choice with no meaning?

  • How does copy protection work?

    - by Yar
    Many programs refuse to go beyond a trial period. Even if they are trashed and then reinstalled, they 'remember' that the trial period has expired. Assuming no contact with a licensing server, what is the general way that most copy protection works? Do programs drop files in random folders on the hard disk that are hard to track down? I know there's no registry on OSX/Linux, but perhaps something similar... ? Or must it be a file/folder? I'm actually not curious from a hacking side but rather from the implementation side, but in any case the question is basically the same.

  • Default Window Size

    - by muntoo
    I'm running Vista Home Premium 32-Bit, though I doubt that matters, in this case. So, how do you set the default windows size? Is there a registry tweak for this? Going to Tools->Folder Options...->View Apply to Folders or Reset Folders doesn't work. So, whenever I open a new window to a random new folder I haven't opened before, I don't want it to take 75% of the screen. Is there any way I could make it open smaller?

  • Using CATransition in a viewController

    - by eco_bach
    Hi I'm trying to implement the ViewTransitions code sample from Apple, but putting all the logic in my viewController instead of my applicationDelegate class. I'm getting a bizarre error when I try to compile. I'm importing QuartzCore in my viewcontroller implementation as #import _kCATransitionFade", referenced from: _kCATransitionFade$non_lazy_ptr in ViewTransitionsAsViewControllerViewController.o (maybe you meant: _kCATransitionFade$non_lazy_ptr) Anyone have any ideas?

  • Calculating length of objects in binary image - algorithm

    - by Jacek
    I need to calculate length of the object in a binary image (maximum distance between the pixels inside the object). As it is a binary image, so we might consider it a 2D array with values 0 (white) and 1 (black). The thing I need is a clever (and preferably simple) algorithm to perform this operation. Keep in mind there are many objects in the image. The image to clarify: Sample input image:

  • Better way to stop/start Webmin and SSH

    - by Jake
    Hi, it would be a good idea to not have webmin running all the time... just start it via ssh when I need it... so, I just stop webmin,and leaving SSH always running... when I need to access webmin, I start it through SSH. but there are lots of people from many country trying to bruteforce my SSH. I can reduce bruteforce using iptables. but because Im feeling still not safe (about 3 months ago), so I stop SSH and leaving webmin always running through custom port. I just start SSH through webmin when I need. and the result, no more bruteforce on SSH, and no bruteforce on webmin (maybe because the attacker dont know my webmin custom port) but I think this is still not really safe. and I cannot restrict access to some IP because I use random IP. If I stop both SSH and webmin, I will lost access to my server. Anyone know the better way dealing with this?

  • How to ignore query parameters in web cache?

    - by eduardocereto
    Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

On the line "inetnum": "122.4.0.0/14", What does it mean for the prefix to be 14? I am using this as a reference Subnet Mask Cheatsheet While resolving it, I get a very wide range which is something like 122.7.0.0-122.4.0.0 I am not able to understand how the IP range is calculate from the subnet mask and I am only able to find calculators online and not a method to solve it.
