That depends on the number of IO nodes, compute nodes, lanes, switches
LNETS, OSSs etc etc. it is hard telling

Thanks for all your answers. I just took some time to understand
how Obdfilter-survey works. It works fine for the Lustre local filesystem.
But is there any Lustre tool that can directly profile the time spent
on the network and on the disk for an application running at the
user level?

Is there any way to benchmark the local filesystem performance of
Lustre on the OSS side? For example, I want to benchmark the random
and sequential I/O bandwidth of the local filesystem of Lustre 2.5
using IOR.
Is there anyway to run IOR directly on its local filesystem without
having
to go through the network?
Thanks!
