Tuning rsize and wsize on NFS for a 10GbE network

Taken from Myricom Site "Do you have recommendations for tuning NFS on a 10GbE network"

1. Use Recent Linux Kernel 2.6.19 or later. CentOS 6 will be a good candidate to implement.
2. On /etc/fstab, you can set rsize=1048576,wsize=1048576
3. You can use the above buffers on NFSv3
4. Do note that for Linux Kernel 2.18 and below, the rsize and wsize is 32KB.
