Hello,
I have a performance problem with an Linux (SuSE8.0) NFS server and a HP-UX 10.20 client. If I try to copy 100 small files (200 Bytes each) from the HP-UX client disc to the Linux NFS server, this takes 25 seconds for the copy and 23 seconds for a rm command. With an HP-UX NFS server and HP-UX client it takes 3.5 seconds. I now about the NFS problem with small files, but is there a way to tune the HP-UX/Linux connection to HP-UX/HP-UX speed ? (or faster)
thanks and regards
Rolf Alfke

The only advice I have is to have the latest nfs release and all patches on the HP client side.
The NFS components with Suse Linux are probably up to date. The NFS component(client) for HP-UX 10.20 is nearly a decade out of date.
This could be a contributing factor to the problem. If you have an HP-UX 11.x box with latest NFS and patches, are the numbers better?

Re: Linux NFS Server and HP-UX Client performance problem
Do the command nfsstat -c check if you have timeouts.
In your mount command from your HP-UX client set the rsize and wsize buffer size to 8192.
i.e.
mount -F nfs -o rsize=8192,wsize=8192 linux:/mnt/export /mnt

Re: Linux NFS Server and HP-UX Client performance problem
Thanks for the tips.
I checked it with a HP-UX11.11 Client. This used 1.2 seconds. I then checked a S700 HP-UX 10.20 machine with newer patches installed. This gave an acceptabel result of 3.5 seconds. So I downloaded the latest Patch bundle for my S800 machine, patched only the nfs software and the result is 3.5 seconds now. This is ok I think.
Thanks again
