Maybe mod_log_firstbyte would suite. Quotes:
mod_log_firstbyte is a module for Apache 2.0 which allows you to log the 
time between each request being read and the first byte of the response 
served. Unlike the total serve time, this index of performance tells you 
how long Apache actually spent loading the file off the disk or 
executing your script: it's independent of client connection speed. It 
makes a great performance benchmark for your server!
The module adds a new option to your log format string: '%F'. This is 
the request-to-first-byte time, in microseconds.

I know it says it's for httd 2.0 in that text, but I'm using it with 2.2 
here (from FreeBSD ports), and it seems to work.
