Re: weird performance problem

Yeah, svn ls is being run on the right url, and it happens with any
url on the repository. The slowness is proportional to how many
elements reside in the directory.

About apache config, I was wondering about that myself as I'm no
apache expert, so I'm attaching my httpd.conf file.

UPDATE: forgot to CC the list. Many apologies to Mark who will get
this message twice. :(

Regards,
Ariel
