Reading this I was reminded of mod_log_firstbyte ... If your application 
precomputes its output and then starts sending (as opposed to outputting 
headers, then doing computation, and then sending output), it might be useful 
to you since it logs the time it takes between receiving a request and the 
first byte of the response being served. Looking for it now, it seems the 
webpage linked from for it is now 
defunct; you may be able to reach its author or find it googling, though.

Another interesting link to follow would be and 
mod_arm / mod_arm4, again depending on your application and needs :-)
