Okay with 2.0.28 beta (on FreeBSD 4.4-RELEASE), I have the following config (rest
defaults):
DocumentRoot "/var/tmp/nostats/here"
<Location /foo/nostat>
SetHandler server-status
</Location>
I count around 6 stat() calls for this single request in regards to DocumentRoot.
Here is my ktrace of a request to /foo/nostat:
