Well this bug fixed in P1 and as i say i had same issues with P1 also this happens on almost idle systems i thought that bug 510586 http://support.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=510586 which fixed in P2 and 8.1.1rc1 is a better feat but i couldn't find long lasting CP also the netapp engineer couldn't find a bug which is relevant to our systems i never tested P2 ( since it released yesterday ) but it might also solve the performance issue

As a word of warning, we attempted to upgrade our C mode cluster from 8.1 to 8.1.1RC1 but ended up rolling back after the storage simply
didn’t
behave correctly for NFS clients. ****

Hi all As a netapp ASP I spent quite alot of my time installing netapp's at costumers site and resolving their issues and I wanted to share
my recent
experience with 8.1 Usually I try to avoid RC release but until recently the fas22xx didn't gave us much choice Once the 8.1 GA released I felt more free to install this release. but after I started to get performance complains from my costumers
I
wasn't so sure After investigating some of the complains I felt that they are justified something is off in system I can't put my finger on it but its looks the system don't perform
as
expected even though the system don't look busy. After opening support cases at netapp one of the engineers told me
that
they also gets alot of performance cases with this release an
even though
he can't find a bug that feets with our logs and perfstat he recommend upgrade to 8.1.1rc1 Following his advise after upgrade I saw major performance
improvment I
mean throughput went up from 70-80 MB/s to 250-300 MB/s and
latency also
went down The same result occurred on more then one 8.1 system after upgrade
to
8.1.1rc1 I saw at least 50% improvment in throughput Today on new system I install I completely skip th GA version an
go
straight to 8.1.1rc1 So my advice if you on this release and suffering from performance
and
don't know if you have enough disks or the right controller upgrade
first
then check
