May I ask how to size pagepool on clients?  Somehow I hear an enormous tin can being opened behind me... and what sounds like lots of worms...

Anyway, I currently have mmhealth reporting gpfs_pagepool_small. Pagepool is set to 1024M on clients,
and I now note the documentation says you get this warning when pagepool is lower or equal to 1GB
We did do some IOR benchmarking which shows better performance with an increased pagepool size.

I am looking for some rules of thumb for sizing for an 128Gbyte RAM client.
And yup, I know the answer will be 'depends on your workload'
I agree though that 1024M is too low.
