Is there a 'simple' guide to getting the most from a NFS4 server
Our servers generally have 60-90 users hanging off them and they
are fine but occasionally things conspire so that the full 180 users
are attached to each one and they get very slow.
I have fiddles with the use_kernel_nfsd_number' and increasing it from
the default 4 to 64 makes a lot of difference but over 128 makes it
slower- I am assuming all those processes exhaust something else
These servers just sit there being NFS4 servers ( for openSUSE
clients ) and nothing else.
