Red Hat 8.0 / Apache 1.3 Bandwith utilization problems

[Rajiv Bhushan <r bhushan attbi com>]

We are trying to use a single client to generate either 10 Mb/s or 100 
Mb/s of traffic.  The clent sends off a rapid fire series of http gets 
(~350 requests/s) for a certain set of files.  The rate is scaled up or 
down to increase/decrease traffic.  We can never get beyond 3Mb/s using 
a 10Mb/s line, and 30 Mb/s using a 100Mb/s line.

Both the server and client are running stock out of the box Red Hat 8.0

The server is running Apache 1.3

If we use 'ttcp' on server and client, we are able to saturate both the 
10Mb/s and 100 Mb/s line

Any ideas as to what tuning parameters of the Apache/Red Hat combination 
could be causing this problem?
