Hi all
First of all, yes I have read the various threads about NFS Performance with VMWare, and I know and get that it is all related to the SYNC writes requested by VMWARE's NFS.
What I don't get however, is why the performance is THAT bad...
I have the following equipment:
- FreeNAS-8.3.1-RELEASE-x64 (r13452)
- Supermicro Server with Intel Xeon E5620 @ 2.4 GHz
- 32 GB Memory
- 24x INTEL SSD 256 GB in 3x raidz1 @ 8 disks
- 1x Gigabit connection
- No ZIL
- No L2ARC
My IOANALYZER (vmware) now tells me with the MAXIOP configuration that my NFS Datastore has a write speed of 86 IOPS (!)
What could be the issue of that?
I have created an iSCSI datastore, and I was able to squeeze 28600 write IOPS out of the system...
Any ideas?
I would expect at the very least 2000 IOPS out of an ALL-SSD system even on an all-sync-nfs-zfs configuration?
Thanks
Michel
