To validate Oleg's claim for reads, namely that they are suboptimal for

Does OST survey run for catamount clients? I'd need some pointers to get
going on trying that. We ran obdecho once, but I haven't personally got
obdfilter device going on xt3 as of yet.
I think Peter suggested running the obdsurvey on the servers.
IIRC your servers are regular Linux systems, right?
There are some instructions for the lustre_survey python script in the KB:
https://bugzilla.lustre.org/show_bug.cgi?id=9383
I'm not sure it's still working though, I know there were related bugs
opened, but I can't find them anymore.
Here we are still using Eric Barton's obdfilter-survey shell script, which
works pretty well, but we only use it on test systems.
