Another idea If you want to calculate this going forward, you could simply use the %T for a custom access log in apache.
http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#formats %T gives you the total time it took to service a request. From there it should be trivial to parse that access_log and determine concurrency at any point for any URL.
