Could somebody guide me on measuring NFS performance on HPUX. I need to evaluate and document performance on NFS. Currently i am using nfsstat...but it is not very clear. If anybody can give me any insight on any other ideas/tools/utils ..etc, it will be of great help to me.
Thanks,
Bgs_bnny

Re: NFS performance testing !
Make a big file and call it 500meg:
prealloc /tmp/500meg 5000000
Copy /tmp/500meg in and out of your NFS file system from the client side and note these stats:
nfsstat -rc (* timeout and retrans *)
netstat -m (* number of requests for memory denied *)
vmstat -n 5 5 (* %idle = 0 or low? *)
nfsstat -s (* readlink and lookup calls nearly equal? 'getattr > 60% then not caching enough *)
nestat -s -p udp (* overflows high ? Not enough nfsd daemons; start more in nfsconf *)

Hi Orlando.
I know that guy. I'll talk to him about getting you a copy. ;)
Send me an email - Private Info Erased - and I'll send you the PDF version.
