Assuming this is a lab (and we can thus ignore bandwidth and latency on the internet link), the expectation is that this kind of scenario for squid will be CPU and network I/O bound, so in order to give any sensible answer we'd need to know what kind of network interface you would use (fast-ethernet? Giga-ethernet copper? Giga-ethernet fiber? Even faster?), what kind of CPU and what kind of system architecture (server-class? pc-class? virtual?) -- /kinkie
