Hi,
We have brand new E450 running Solaris 7 and NetApp Release 5.3.4R3 and we are planning to use NetApp as a ClearCase VOB storage. Both are on 100mb/full switched fast Ethernet.
I was trying to play with Postmark to identify what is best for performance, like NFS2 or NFS3? TCP or UDP? What values for rsize or wsize?
r/wsize TPS read write -------------------------------------- NFS3 UDP 8K 38 223.42 720.64 NFS2 UDP 8K 3 13.81 44.53 NFS3 TCP 32K 2 12.67 40.86 NFS2 TCP 8K 2 13.14 42.39
a) For some reason, the best results I've got was with -o vers=3,proto=udp. NFS2, or NFS over TCP looks like a joke... It's like 20 times slower.
b) There is no way to use w/rsize=32768 with NetApp with NFS3 over UDP. Why? I can do it when mounting from Solaris.
Any comments?
Thank you.
