We are running subversion 1.6.17 on a vmware hosted server. We recently
reconfigured the server to give 4 virtual CPUs (up from 1), and a
significant amount of memory.
In order to spruce up our performance a little, I looked into the use of
memcached with subversion again, found the correct config parameter, and
set it up. Our server is running Ubuntu 10.04, Apache 2.2. Access
mechanism is http (of course). The client used is running Ubuntu 11.04,
and svn commandline (1.6.17 also)
The results were interesting, to say the least.
Checkout of a tree, about 250M in size:
Without memcached, 1 1/2 to 2 minutes, varies with server load
With memcached, 12 minutes (!)
Update of the same tree,
Without memcached, 9 seconds
With memcached, 14 seconds - repeated several times, similar results.
I am not sure what anyone else's experience is, but we will not be
enabling memcached for subversion any time soon.
