I'm willing to contribute... anyone have any favorite numbers?  I'll give
some stuff a try...
I'm actually more interested in size issues than speed issues... considering
I just got a 933MHz PIII server brand new from Gateway for $500, my solution
to speed is, buy a new machine, it's cheaper than the labor to optimize your
software :)

True, but without a system analysis, who knows if that's a real bottleneck?

Anyone know what Apache does for this case?  And/or why ZServer doesn't tae
the most efficient solution?
