stopped and started it many times. Load is fine (2-3) so long as I am
not serving sites...

It seems that it was already started. Can you stop it and check node's load before starting it again?

Hi List,
I am still struggling with my setup. One server is working reasonably
well for serving websites, but serving sites from the 2nd server is
still using excessive amounts of cpu; a bit of which is gluster, but
most of which is apache.
Gluster docs mentions client-side-profiling:
https://gluster.readthedocs.io/en/latest/Administrator%20Guide/Performance%20Testing/#client-side-profiling
specifically:
"In short, use client-side profiling for understanding "why is my
application unresponsive"?"
Great, I think this is what I want. instructions are:
*gluster volume profile your-volume start
*setfattr -n trusted.io-stats-dump -v /tmp/io-stats-pre.txt
/your/mountpoint
*This will generate the specified file on the client
Okay:
root@moogle:/usr/src/gluster-profile-analysis-master# gluster vol
profile webisms start
Profile on Volume webisms is already started
root@moogle:/usr/src/gluster-profile-analysis-master# setfattr -n
trusted.io-stats-dump -v /tmp/stats.txt /Computerisms
root@moogle:/usr/src/gluster-profile-analysis-master# ls /tmp/stats.txt
ls: cannot access '/tmp/stats.txt': No such file or directory
thought for sure I am doing something wrong, so I had a look at the
gvp-client.sh script, and it appears I am doing the command correctly,
there is just no output file. Am I missing something? or is this an
outdated methodology that no longer works?
