[lustre-discuss] Benchmarking Lustre, reduce caching

[Athinagoras Skiadopoulos]

Hello,

We are using Lustre in our cluster as an external service and
would like to measure the write/read performance we can achieve.

Right now, we are creating a number of files, and iteritavely:
- pick a file to open
- write/read it in 1MB chunks (block size)
- close it

Each of our servers has a 3000Mbps bandwidth,
but we are often reporting higher read/write throughput.
There should be some caching involved.
What would be a good way to alleviate this?

Thank you in advance.
