[Lustre-discuss] Benchmarking small file performance

[Kumaran Rajaram]

Rick,

I would suggest "fileop" benchmark in the iozone benchmark suite to
measure metadata performance. In addition, iozone comes with parallel
version to run multiple instances across clients.

http://iozone.org/

Spew is another good benchmark to measure small and large file I/O
performance
