You might just be hitting the limits of one :squid server. : snip 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.
