Was this noticed also on 8.1p1?  Looks like there were some good fixes in the p release.

Thanks in advance.

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
