NFS client problem with HP-UX 11.00

[Naveen Shetty]

I have netapps F840 as file server, N4000 4CPU 4GB ram machine as client connected two 1000-SX card. Read too slow compared with local disk
or SAN box. Executing dd for read gives only
33MB/sec where as same read over jbod/san box
gives 55MB/sec. Simutaneous running of dd commands gives 65MB/sec equivalent to jbod/san box.I use NFS v3 for mounting with rsize=32768 & jumbo frames.All NFS,Network patches upto
Aril 2001 have been installed.

So whats the problem ??

Did you seriously expect filesystems mounted over NFS to perform as fast as local disks on your N-class ?

I would love to have that NFS speed... ;)

I have 500GB Oracle DB running over it. Initially we where on HP's FC60 with Raid 5, but the write was too slow (We have 30% write & 70% read).So we migrated to F840 which imroved our write but decreased read performance.Is there
any options available on HP to boost NFS read
performance via Gigabit card.
