VMware on Linux NFS Server

Hi!

I am building a small cluster by using an NFS Server under Linux. I tried to tweak some parameters in order to get the best performance. This is what I got so far:

- NFS Server has 3 NICs bonded

- Vmware Server have 2 NICs bonded

- Read Performance is at around 110MB/s (100-115)

- Write Performance is at around 100MB/s (80-115)

- on the NFS Server the storage runs in an RAID6 array

The performance was tested with reading and writing 1GB files. When using a file with 5GB the performance at about 60MB/s read and 50MB/s write.

I also tried jumbo frames. But any other setting than MTU of 1500 made the performance to go down a bit (yes the MTU was set on both sides).

Any suggestions?

Can you post some details such as distro, kernel version, export options and storage layout? I'm unable to even get that good a speed on linux NFS.

also, I'm not sure how well ESX 3.5 can use bonded nics with nfs, at the very least you'd have to run benches in more than 1 guest at the same time. I know that it doens't with iscsi, and no jumbo frames in the vmkernel either.
