Hi I have several web servers that are attached to a Netapp (network appliance) unit via NFS-3. A few servers are 5.5 and a few are 6.1 for comparison testing. All seem to have lousy performance. When going through the issues with Netapp, the reasons given were that we have too many GettAdr/Lookup requests compared to actual reads. So all the NFS IOPS are being used up by these requests. As soon as the webservers get busy, requests pile up. I have tried everything I can think of. The web servers are even mounted read only with no help. My current mount options are: filer:/vol/fvol31 /home/13/13 nfs ro,noatime,-r=32768,-T,-b,-R0,-i,-D2,-L 0 0 I have tried plenty of others. an example nfsstat -c 2 (while working ok) GtAttr Lookup Rdlink Read Write Rename Access Rddir 4357 2976 0 125 0 0 3425 0 4173 2836 0 115 0 0 3288 0 4254 2912 0 106 0 0 3344 0 3668 2528 0 99 0 0 2880 0 3992 2746 0 101 0 0 3136 0 3916 2706 0 93 0 0 3080 0 3748 2551 0 106 0 0 2948 0 4121 2851 0 86 0 0 3231 0 Any advice for sysctl tunes or anything else would be much appreciatted!
