CPU load has very little to do with the performance of a firewall.
From list archives, first from Manuel Kasper, second from Fred Wright:

More precisely, they don't indicate interrupt time. I believe they *do*
indicate kernel time spent at process level (i.e. system calls), but most
packet processing is done at interrupt level. And any reasonably portable
way of measuring the interrupt time would probably involve more overhead
than one would like to see. Especially if the processor is slow enough
for it to be an issue. :-)
Also the snmpd in m0n0wall doesn't appear to have any load numbers.
See attached snmpwalk output from m0n0wall 1.1.
Unless you have a 10+ Mb internet connection, I don't see the 4501
speed being an issue. Anything odd in your system logs?
