Yeah, we use it almost everywhere.  The only exception is a video store
where the files aren't terribly compressible.  As you might imagine, it
uses considerable CPU cycles on the client but it also reduces the
bandwidth required.  Assuming the CPU can keep up, it may well relieve the
network bottleneck.

Ah, sorry yes.  I was confusing myself between Mb (usually Megabit) and MB
(usually Megabyte).  I see what you mean now, the above is 75MB/sec to the
localhost.
