[Lustre-discuss] Questions about benchmarking Lustre's local filesystem

[Ron Croonenberg]

wondering why you would want to do that other then checking to see if 
there is something wrong with some chunk of hardware?

If you want to test the speed of the Lustre fs it really depends on how 
many OSSs, OSTs (and OSTs per OSS) you have (and what other hardware 
you're using) and how you set your striping depending on your 
applications.  Best performance will probably be N --> N worst 
performance probably strided writes N --> 1. Also multiple access from 
one client seems to slow stuff down.
