We've tested such things with back-to-back 100BT, to a NetApp
filer. Worked quite well. The key thing is that all the seeks to find
data are embodied in just one NFSop, so all that work is offloaded
onto your NFS server. Additionally, all writes can be consumed
instantly (if you've got NVRAM or you're using NFSv3) by the server.

We also experimented with a RAID-3 controller with large amounts of
cache. That also worked very well for Squid and we didn't manage to
stress it at all (disappointingly.)

Well, you don't need any NFS locking because nothing else is sharing
the cache.
