nfs to NAS server slow.

Hello , Hope everyone had a good weekend.

I nfs mounted a NAS server to one of our hpux servers. But the performace is soooo slow when transfering files to it. I have been reading and saw that there are some patches:PHNE_22125 s700_800 11.00 ONC/NFS General Release/Performance Patch.
And I also read a an HP doc that that says:
To speed up the writes to a Domain NFS host, mount that host using the
mount options "rsize" and "wsize". These two options will set the packet
size to n bytes, allowing the Domain buffer to handle the packets in a
timely fashion. For Example:

mount -o soft,rw,rsize=1024,wsize=1024 apollo1:/home /apollo_home

I was wondering if anyone had this issue with NAS servers and if theese solutions work.

Hi Richard:

First of all, yes, apply the latest NFS patches that are applicable to your OS. Generally, rsize and wsize do well somewhere in the 4096 (4k) to 8192 (8k) range. However, before you do anything else, don't overlook the obvious. Make sure that your speed/duplex settings are hard-set on both ends of each connection. Check those on your NAS server to switch as well. Normally these NAS servers perform like toasters and you just connect them and they work quite well.

Thanks Mr.Clay
I now have my lineup on what to do to work out our issues with the NAS.
