Hello!
We've got one MDS (Lustre 2.0) with 4 processors (Intel(R) Core(TM)2
Quad CPUQ9500 @ 2.83GHz).
Our CPU usage is HIGH - 80-100% .
With top command we see:
PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND
2973 root 15 0 000 R 35.0 0.0 1509:09
Dear Dilger,
Thank you for your reply ! But I still have something unclear.

Hi,
More details are needed here. What type of interconnect are you using?
What are your clients doing? etc.

Hi,
I am installing a Lustre system and I wanted to measure the OSS
performance.
I used the obdfilter_survey and got very low performance for low
thread numbers when using the case=network option
System Configuration:
* Lustre 1.8.6-wc (compiled from the whamcloud git)
* Centos 5.6
* Infiniband
The case=network part of obdfilter_survey has really been replaced by
lnet_selftest.
I don't think it's been maintained in awhile.
It would be best to repeat the network-only test with lnet_selftest, this is
likely an issue with
the script.

FYI, there is some work being done to clean up obdfilter-survey. See
https://bugzilla.lustre.org/show_bug.cgi?id=24490
If there was a script issue you might try the patch from that bug to see if you
can reproduce.
