[lustre-discuss] Tunable parameters for caching and thread on oss side

I am working on tuning Lustre filesystem. So I wonder what the parameters
we can tune for caching on the OSS side.  I find one parameter
"readcache_max_filesize" for OSS. Are there any other parameters?

The same question for OSS thread count. What are the parameters for thread
numbers on OSS we can tune and take effect on the performance while an
application is running?

My Lustre version is 2.10 and is installed on CentOS.

Thank you very much!
