Re: Preferred Subversion 1.13 MPM

hello friends,

Thanks for replying - no hard feelings for getting fast up from the seat
:)

I was thinking the MPM might have a saying, since the process management
of a certain worker might be optimal for the way Subversion operates - i
notice that many requests are sent to the server from even smaller
operations in an SVN client.

What i have picked up from your bag of tricks - is LDAPcaching - now i
referred to apaches docs for mod_ldap and defined cache TTL to 1 hour
which is reasonable for my herd of users. It seems that it might have
had an impact, but i have to have a users verify that it shortened
runtime, and how much it possibly was.

But im chasing anything that i can on this, and surely i have a lot to
learn about how to properly operate Subversion for production purposes.
So what MPM have you guys configured for apache? -and what sort of other
information could you be interested in Stefan?
Currently i am using event MPM..
As background, yes i authenticate on LDAP, no encryption towards AD, and
i interface AD directly on IP, so no delay looking up DNS. Also i only
host the service via mod_dav_svn on http for the local network, so
theres no https encryption in play in the webserver. I have no per
directory restrictions, if a user has access to / then he has access to
all repos underneath - now then i just host several vhosts with
different having different restrictions.. so in many ways its a very
simple solution.

cheers
Carmen
