Default rsize and wsize for nfs v3

The /etc/fstab entry used by my nfs client is {server_ip}:/home/{server_user}/{server_path} /home/{client_user}/{client_path}

I wanted to know the rsize and wsize values used by default. I wanted to try out some benchmarks with various values smaller and larger than the default values so that i can arrive at an optimum value for my read heavy setup.

Don't modify rsize and wsize. Recent NFS servers and clients will work out the best value for you and will probably do a better job than you would as well. :)

If you are on a Linux box, take a look at /proc/mounts. You'll find the current value there. If you specify no value in /etc/fstab, that will be the default (or at least, a value that is considered sane by the system).
