... and as a result it's a *LOT* faster!  :-)

I've been using it happily on several production Squid servers for the
past few month and a half.

Unfortunately the two busiest of them are running FreeBSD due to the
vastly newer (and thus far less buggy and somewhat more efficient)
AIC-7899 driver in FreeBSD (the same one that was over a year ago ported
to NetBSD-current and won't run properly on the machines I have
available to use [w/Intel STL-2 motherboards]).

Before splitting the load between the above two servers I stress tested
one of them with the full load and it sustained, for lengthy peak
periods of time, throughputs of over 850KB/s and over 160 requests per
second, with no evidence that it was maxed out.  Estimates based on the
extrapolation of the cache bake-off results suggest that without diskd
the same hardware would manage only 1/4 the throughput.
