  • Copy past speed very slow for a large number of tiny files on Windows but not on linux

    - by Arno2501
    I've got this folder which contains 15'000 of tiny images (around 400 bytes each). If I copy past this folder on my laptop (Windows 7, i7 latest gen, superfast ssd) it takes about 30 seconds (yes for 7 megs !!!) the average transfer rate is 400 KBytes / second which is so slow. I mean my usual transfer rate is more like hundreds of MBytes per second !!! I get the same problem on my servers (Windows 2003, 2008 /r2) and on every Windows box that I could get my hands on. On the other hand if I do the same on a linux box (debian base, Ext3 FS) (which runs on the same SAN than all the windows servers I've tested) It's nearly instantaneous !!! I'm pretty sure the size / number of the files may stress such filesystem more than another but such differences !? Why is that ? Why is it so slow on the windows boxes (more that 30 sec for 7 MB) and so fast on the linux ones (one sec or so) (I mean this was not a hardlink that I've created it was a true copy). Is it a normal behaviour or something unusual ?

  • Can I rename a file that is open on Windows XP?

    - by Radek
    I want to programatically rename a file and it could be open. It's a log file. When I was testing my code the rename part didn't work because the log file TestPro.log was open by the TAF (Test Automation Framework). When TestPro is running and I try to delete the file I get the error "Cannot delete because is being used by another person or program." Is there any way how to rename a file (programatically) that is open the way the log file was?

  • MongoDB on 128mb 32-bit VPS (plus Tornado and Redis)

    - by apito
    i am curious about how mongodb will perform in a limited vps. specifically, i'll deploy this configuration on 32-bit ubuntu 9.04 server with 128Mb memory (UPDATE: now i'm considering 360mb too). nginx and redis three instances of tornado apps (one is for mobile site; limited app, not my primary audience); has around 8 Collections. social webapp for my community. mongodb all beside mongodb seems to have small footprint. memory-mapping-wise, i dont know how mongodb will behave. i know it's a little bit a stretch to use this kind of config on a tiny vps, but that's what i can afford for now. i expect to have.. hmm.. maybe ~50 15rps. i did my homework doing a lot of frontend optimizations and yslow says grade A 91 (ruleset V2) :-) anyone willing to share experiences? eg. how big the data set size when mongo hit the ceiling, performance when mongo do a lot of disk IO, etc. thanks. UPDATE: this is my pet project. i'll get back to you when i have next spare time to do same httperf in a vbox with exact spec. suggestion how to do stress testing welcomed. i'm new to this kind of stuff.

  • Simulating proxy in VMware

    - by BloodPhilia
    I'm currently testing out a new proxy system that I'd like to try out on my own computer. Because I do not have an additional PC available, I though I'd do it with VMware. Here's what I'd like to do: The physical computer is to make an internet connection using the VMware proxy and not the router. Is this (1) possible and (2) if so, how am I to accomplish this? Thanks!

    - by Aidan
    I wish to use vagrant and possibly VeeWee to construct and maintain virtual machines to automate some testing of servers etc. I am having problems getting them up and running on windows. Is there any are there any takes-nothing-for-granted setup blog posts or instructions anywhere? I live in a Microsoft world so all this Ruby/Git is new (and exciting!) to me but it does mean that I could do with everything being spelled out to me in excruciating detail! Cheers

  • How to reinstate toolbars on an embedded PDF with Firefox and Adobe Reader plugin?

    - by Grundlefleck
    Using Firefox I was viewing a PDF file embedded within a web page, with the toolbar available. After right-clicking to deselect the toolbar (I was testing something) I cannot find a way to reinstate them. Since the toolbar is enabled by right clicking on the toolbar area, when it's disabled, it's not obvious how to reenable it. When the toolbars have been disabled and no longer visible, how do you reinstate them? Version info: Firefox 3.6.3 Adobe Reader 9.3 Kubuntu 10.04

  • Max. Temp. on Intel Burn Test for Stock Dell Precision T3500

    - by HK1
    I'm troubleshooting an issue on a Dell Precision T3500. As part of my troubleshooting I've decided to try running a stress test using Intel Burn Test software. This machine is a stock configuration with 12GB of RAM and a Xeon W3670 processor (nothing overclocked). When I run IBT using the standard mode, SpeedFan reports a processor temperature in excess of 80C. I've seen numbers as high as 90C but even at that temperature the machine does not become unstable or crash. However, it seems way too high. This processor has a TCase of 67.9C according to Intel's website. I'm guessing that means I'm in the danger zone any time I go over that temperature. I've checked the cooling system and everything looks fine. I've even took out the heat sink and reinstalled it with new thermal compound. This did not appear to make the problem better or worse. Is there a discrepancy somewhere here in the way temperatures are measured or displayed? I've also tried using HWMonitor from CPUID and it reports the same temperatures. Should I just let the Standard Test go and disregard the temperature outputs?

  • The real differences between Red Hat Enterprise Linux (RHEL) and CentOS

    - by w00binda
    I know that "the vast majority of changes made (by CentOS team ndr) will be made to comply with the upstream vendor's re-distribution policies concerning trademarked names or logos" But I'm looking for a way to measure the real differences between RHEL and CentOS. My goal is to demonstrate "scientifically" that is possibile to use CentOS for development and testing purpose and use RHEL in the production environment. Any suggestion? Thanks in advance.

    I'm testing Windows 8 RP. Installed tens of apps from market. What I wanna know is, is there any way to save (or maybe sync with Windows Live account) installed app list, and install these saved applications in future - RTM version of OS? I mean, somehing like on Apples' devices - icloud features function that I'm talking about. You can install apps on iPhone and sync with iCloud account. Then you can re-install these apps on another device, which signed in with your login into icloud.

  • How can I use dig(1) to test GeoDNS resolution for a specific IP?

    - by cnst
    There's a rumour that public domain name resolvers, like Google Public DNS, are still supposed to work with GeoDNS, because there's some field in the requests that lets them specify for which IP address they are doing a resolution, thus the authoritative servers can give a given resolver different resolutions for different final clients. What's this whole thing called as far as RFCs go, and how does one mimic such resolutions, for testing purposes, e.g. with dig(1)? Else, what other tool is available to accomplish said task?
