I do the same...

I suggest you to upgrade to a GBit network.
I have here a minimum of 80 MByte/Sec using NFSv4 with
samba3.private.tamay-dogan.net:/home /home nfs rw,bg,hard,intr,tcp,vers=4,rsize=16384,wsize=16384 0 0
in the /etc/fstab on the workstations

Realy crap!

Even CHEAP (!!!) 36port GBit Switches with TrendNet Cards will give you
at least 40-50 MByte/Sec. Using a professionel switch, which cost
arround 800 Euro, and Intel GBit Desktop Cards give you the FULL
performance of 80-100 MByte/Sec.
I stronly recomment to this upgrade since you are working in a profess
sionell environement
And even if you want like to upgrade all, install in the Servers GBit
Cards and use a GBit switch. and let the workstations be on 100 MBit.
This schould work perfectly too and reduce costs enormeous.
