wich kernel variable affect NFS performance?

Hi all:

I磎 dealing with a weird problem on solaris 10 (01/06) Sparc with patches... we are sharing some solaris partitions with windows NFS clients (via SFU 3.5) My problem is that I have NFS performance issues, according the docs if I have >40% getattr (I磎 ussing NFSv3 server and client over TCP transport) I have to increase attribute caching.. but nobody tells me which kernel variable affects this one.

I have increase ncsize and maxusers without luck... can somebody tell me which variable affect attribute caching?

PD: by the way the filesystems are 58MB and 60MB . with one nfs client while I resolve this issue..

i think ncsize is the one which determines the size of your file cache.For a newly booted system, or a system which uses the NFS mount very rarely its common with a low cache hit.. 7/M.
