Hi Folks,

I have one box which serves 4500 users and saturates a
45 Mb (T3) Line.
Sadly enough due to politics that box will be phased
out in favor of a commercial solution..
During normal working hours the median is 28 Mb/sec and
during busy moments it will reach and stay 44.xx Mb/sec
for as long as it takes. The hardware is a HP DL360 G3
Xeon 2.4 Ghz with 1.5 GB RAM and 2 x 15K hd's. OS is
FreeBSD tuned.
My point is to clarify that 20 Mb/sec is by long not the
limit of a single squid instance.

Regards,

LJ
