For read, I used if=/h/zero and of=/dev/null. Flags for reading: iflag=fullblock conv=nocreat and for writing: oflag=direct iflag=fullblock conv=nocreat,notrunc To test the CPU bounding, I just tried limiting the clock speeds on the client and server. Limiting the linux-server's max cpu-speed had the most affect on performance: (limited to 1.6GHz instead of 2.4GHz) (33% limitation)...

What is the maximum speed for download from a samba share? I have a 100 kbit/s Internet The maximum speed for a download from my  webserver with samba is about 25.000 kbit/s The bottleneck is the samba access.  Without samba  I can download with 100 kbit/s So the question? is it possible to get more speed or is this the maximum speed with samba? I tried a lot of hints for samba tuning but

Hi, I need some help on how to manage the "full" log file. It's getting quite large now and I'd like to clear it. Is there any simple command for this or should I just delete the file (need to be sure this won't affect the system). Also - how do I keep the log file from growing so large? Thanks! Regards, Jan

...esystem. I did some tests using dd, with different block sizes, directio and none, etc. The test file is about 1Gig in size, and spread across 25 fragments (found using filefrag). Block size is 4k. I have also tried setting readahead buffer using blockdev , from 256 to 32767. time /root/dd conv=nocreat ibs=4096 obs=4096 if=/sam/cache/test/test3 of=/dev/null The best real elapsed time I get is about 23.5s. If I dd the same amount of data from the disk device itself, I get about 18.5s, which matches what hdparm -tT gives me. Comparing strace outputs, I can see the read system calls reading fro...

...log files with the default logrotate setup (or even a modified one) from RedHat? The default setup is to move the files to another location, create a new file for Samba to fill, then send the daemons a HUP signal. I've tried some of the options that can be used in the logrotate.d/samba file (nocreate and copytruncate) without success... Currently, I'm allowing the default behavior without sending the HUP signal (the file move and the creation of an empty log file) then having a cron job restart the daemons by killing all the processes with a signal 9, and restarting. Just wondering if t...

This patch is incomplete but it illustrates the idea. virt-sysprep is rewritten as a modular tool in OCaml. Only the 'utmp' and 'hostname' operations are implemented at the moment. Rich.

I''ve recently re-installed an X4500 running Nevada b109 and have been experiencing ZFS lock ups regularly (perhaps once every 2-3 days). The machine is a backup server and receives hourly ZFS snapshots from another thumper - as such, the amount of zfs activity tends to be reasonably high. After about 48 - 72 hours, the file system seems to lock up and I''m unable to do anything
