1.) Add "%D" or "%T" to your access log format.  That will log info about
how long the request took to process.

%D - Time taken to process the request, in millis
%T - Time taken to process the request, in seconds

2.) This valve can also help.  It'll dump a stack trace when a request
takes longer than the configure threshold.
