15.2 mod_status and ExtendedStatus On

If you build in mod_status and you also set:

ExtendedStatus On

in httpd.conf, on every request Apache will perform two calls to gettimeofday(2) (or times(2), depending on your operating system). This is done so that the status report contains timing information. For highest performance, set ExtendedStatus Off (which is the default).
