slow httpd response

[Keith Mastin]

apache-1.3.27-2 on a redhat-7.3 smp system. Running php, perl on the web
server.

I'm experiencing really slow httpd responses from my webserver. The
machine it's self is running smooth and fast. The top portion of top:

 12:23pm  up 135 days,  5:13,  3 users,  load average: 0.01, 0.05, 0.01
116 processes: 115 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states:  0.3% user,  0.4% system,  0.0% nice, 98.3% idle
CPU1 states:  0.1% user,  0.1% system,  0.0% nice, 99.3% idle
Mem:  1289260K av, 1220880K used,   68380K free,       0K shrd,  198116K buff
Swap: 2096472K av,    1704K used, 2094768K free                  743132K
cached

Nothing significant is showing in my error or access logs or messages.
ssh, ftpd, rsync all work smooth and fast. So does mail. But the web
server has become a dog. Config files all look okay.

The question I have is where to look next? How to track the specific
process it's crapping out on?

It's a multi-domain system with most user access limited to ftp with
vsftpd. It's a pretty tight system security-wise, and it's clean.

TIA
