Performance definitely should be _much_ better. 486DX4/100 is fast
enough machine for such tricks. Link is 100Mbit ethernet, everything
is loaded.

Tests are done with various big files (>1.5Meg). Speeds are in K/sec

Server 2.0.X, client 2.0.X

FTP:
server pentium/100, client pentium/100: 3700 (cache-cold), 5400
(cache-hot), 4100 (cache-cold), 4400 (cache-hot)

NFS:
server pentium/100, client pentium/100: 1186 [bogus because already in
clients cache?], 320 (cache-cold)

Oops, oops, nfs performance is really bad.
