I recently installed 2 Sun V210 servers (Solaris 8 HW4 update) with 1 week
old patch recommended cluster. I am noticing painfully slow nfs performance
to a volume mounted to a NetApp filer. When I try to access the same netapp
volume from a Solaris 9 machine (Sun 220R with Solaris 9 U7 and 1 week old
patch cluster) I see great performance.
 
Where am I going wrong or what can I begin to check?
 
I have hard coded the /dev/bge0 settings and cisco switch to match as
follows
 
ndd -set /dev/bge0 adv_1000fdx_cap 0
ndd -set /dev/bge0 adv_1000hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1
ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_10fdx_cap 0
ndd -set /dev/bge0 adv_10hdx_cap 0
ndd -set /dev/bge0 adv_autoneg_cap 0
