similar to: ext3 filesystem performance question

Hi there. First of all, I'd like to congratulate to developers for making a free specification and LGPLed decoder/encoder. :-). I did some test, ripping 17 tracks of my CD and converting them to both MP3 and OGG format. MP3 encoder/player was Lame 3.70 OGG encoder/player was from a Saturday nightly tgz package. ------------------------------------ MP3: LAME-3.70 mpg123-0.59r-4 MP3: lame -S

Hi! Anyone else experiencing performance problems when using the new monorepo? My experience is that performance of gitk (and git log) sometimes is really bad when working in the monorepo. I've mainly seen it when using gitk on specific files/directories, but since gitk seems to be using "git log --no-color -z --pretty=raw --show-notes --parents --boundary HEAD -- <file>" it

...but 2.4.3 worked fine. this is linux 2.4.18 with glibc 2.2.5 and libz 1.1.4, if it matters, on both source and dest. apparently something about trying to send a file ending with .iso gives rsync a fit if the -z [compress] option is used. $ time rsync -Pzv --stats cd1_en_binary.iso mail.cheek.com::root/home/ericom Password: cd1_en_binary.iso rsync: error writing 16385 unbuffered bytes -

Otherwise, the problem is not obvious.

i found two article said that rsync -a --delete empty/ a1/ will much more faster than rm when deleting millions files: http://linuxnote.net/jianingy/en/linux/a-fast-way-to-remove-huge-number-of-files.html http://www.quora.com/File-Systems/How-can-someone-rapidly-delete-400-000-files but my test gets opposite result, and i think it's impossible on theory. i use the command 'for i in

When I copy a file(13Megs) from /home/ to /tmp/, sync takes almost 2 minutes. When I copy the same file to /usr/local/, sync returns almost right away. Both filesystems are ext3 and are on the same harddrive. When sync is running, the harddrive light stays on but I don't hear it doing anything. dmesg doesn't show any errors either. Below is the `time` output for each command. If you

I used "/usr/bin/time" to time how long it took to join a DC to our domain. It took 9 hours, 54 minutes and 16 seconds.

Hi, does Centos-5 support the GFS filesystem and the RedHat cluster suite? I did not find anything in the FAQs.

I got used to rsync's -v --progress option so much that I used it instead of rcp even to simply copy files across the network. I dont like software that doesnt talk to me! :-) I like the percentage bar that --progress gives! To my surprise, I found that, when dealing with 1GB+ files, rsync is 4-5 _times_ slower than rcp. Yes, I know that rsync is optimized for sending deltas to a file

Hi, having running centOS-4.4 on a really fast machine (16 GB memory, 8 Opteron CPU's, SATA drives). Then making an update by using the Centos-5 CD's. The start was fast, but during update, the installer spents a very, very long wallclock time during selinx updating: for about 1/2 hour the updater runs in a restorecon/find sequence. And at the end, before the MBR is written, it spents

Hi, using centos 4.4, and freenx-0.5.0-10.c4 and nx-1.5.0-1.centos4 on a 8 CPU Amd Opteron system. If I access this system by nxclient-1.5.0 from some workstation (FC6) with Gnome desktop, then after a successful login the X11 windows have no windowmanager frame, so a handling of the X11 windows is very difficult. This effect does not appear when acessing the centos system by xdm. Is this a
