Whilst this is a common problem, this is unlikely to be the case for
Apache (or an httpd generally).

Check the networking parameters (MTU and window size) on the firewall.
If they seem OK, the best approach is to run tcpdump on the firewall
to check what's actually occurring.
Also, be sure that you don't have a blanket firewall rule blocking all
ICMP packets (although I don't actually know whether that would slow
TCP down, or just kill it altogether).
