Note also that ExtendedStatus causes some additional overhead for =20
every request, which is why it's generally turned off by default.  =20
It's not bad, just something you should be aware of.

 =46rom http://httpd.apache.org/docs/2.2/misc/perf-tuning.html:

   If you include mod_status and you also set ExtendedStatus On when =20
building
   and running Apache, then on every request Apache will perform two =20
calls to
   gettimeofday(2) (or times(2)  depending on your operating system), =20=

and
   (pre-1.3) several extra calls to time(2). This is all done so that =20=

the status
   report contains timing indications. For highest performance, set
   ExtendedStatus off (which is the default).

Yours,

John
