"svn log" is too slow

[Falls Huang]

Hello!
I am running subversion(1.1.4) with the DAV module under apache2 and
my subversion server is P4 2.4G/512M sdram. The normal operations like
check in/out etc are fine, but I found that
"svn log http://xx.xx.xx.xx/repos" is very slow －－－ it almost took me
15 seconds ( the subversion repos has 5000 files ).

I have searched this mailling-list and set "SVNPathAuthz Off" in the
<Location> of dav_svn.conf , but the "svn log" is still slow . How
can I solve this problem ?

thanks and regards,
Falls Huang

PS. if possible please CC me as I am not on the list(but do check it
from time to time).

How long does it take to run 'svn log file:///.../repos' directly on
the repository?

"svn log file:///.../repos" is very faster than "svn log
http://.../repos" , it only took 1-2 seconds.

And during the "svn log http://..." , the CPU usage shoots up to 100%
with 97% used by Apache2.

Btw:
My subversion server is Debian Sarge.

I use svn log --xml to gather data that I build into some statistics/summary
reports, and have also observed that running it against http:// is
immensely slower than running it against svn+ssh:// or file:// (which are
actually almost comparable). I assume there must be some extra network
turnarounds or similar that drag the process down via DAV. So if that's an
option for you, you might try it...
