[lustre-discuss] Benchmarking Lustre, reduce caching

[Ms. Megan Larko]

Hello,

The caching could be skewing your performance results.   Try writing a file
larger than the amount of memory on the LFS servers.

Another nice item is the SuperComputing IO500 (and IO50 for smaller
systems).  There are instructions for benchmarking storage in ways which
can compare to other results for a good idea of the performance ability of
your storage.   There are also ideas on avoiding caching issues, etc.
(Ref io500.org )  Disclaimer:  I am not associated with either
SuperComputing nor the IO group.

Cheers,
megan
