Poor NFS read/write performance on OpenSuse 10.2 2007-05-02 - By Michael Taylor
Back
I know OpenSuse 10.2 is not enterprise software, but I have been running Suse
on my Thinkpad since 9.1 days and prefer having the mobility and desktop
packages available.
I have several NFS shares mounted with the typical oracle NFS options (rsize
=32768,wsize=32768,hard,actimeo=0), and performance has always been terrific.
After upgrading to OpenSuse 10.2 (building fresh after a hard drive failure),
any actions over NFS are terrible. My 2 hour backup now takes 7 hours, the
system locks ups for 5-10 minutes while reading or writing over NFS. I cannot
watch any movies over NFS anymore without the system freezing.
Any idea what changed NFS wise between 10.1 and 10.2? Are there any additional
mount options I should use to get back to the pre 10.2 NFS performance? The
firewall is configured to allow NFS Server on the host and NFS Client on the
client.
Thanks,
-Michael
