Many thanks to those that replied with suggestions. It turns out to be a bug in the NetApp software version that I am running. The Solaris 9 machine that worked great was reverse dns'ed. The Solaris 8 machines were not. Since they were not reverse dns'ed the netapp was failing with a gethostbyaddr call and thus causing the slowness. The solaris 8 and 9 differences caused me to go down the wrong path, but eventually truth prevailed. The work around is to reverse dns the servers or add them to /etc/hosts file on the filer itself. They have also fixed something to prevent this in a later release of the software. Once again, many thanks Ryan _____ From: McEwan, Ryan Sent: Tuesday, September 28, 2004 2:24 PM To: 'sunmanagers@sunmanagers.org' Subject: Weird NFS performance problems on solaris 8 and netapp 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 _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Wed Sep 29 12:29:26 2004
