Your problem may be a network problem, not Apache/Mod_perl.
Check with your upstream provider and have them do a bandwidth analysis. Here is why. I've strobed your network and the return time latency seems to be high. It would appear that you have about a 28 ms latency overhead in/out of your network. That is not a good sign. This is on top of what appears to be a standard 1.54 - 2.0 Mbps line. If your upstream feed is more than a T1 or E1 then you need to have a talk with your upstream. I suggest invest some time in bing. (bing not ping) Of course I'm looking at this through about 20 hops and because of that most of my information is inconclusive. I have noted that codix-pri-gw.uk.insnet.net, which appears to be an assigned router by your upstream, appears to be dropping packets. I get a 40% packet loss when I test to that address and beyond. Anyway, SWAG if this helps, good. If it did not help,... don't blame me, I'm not in the UK.
