OSQA with memcached cache

Question

I have OSQA up and running with the file cache backend enabled, and it’s a little sluggish in places. I’d like to use the memcached caching backend, but I have been unable to find any instructions on how to configure this in OSQA.

What should CACHE_BACKEND be set to in settings_local.py to use memcached? Are there any other steps to the configuration?

First thing is having memcached up and running. Then you need to install the pyhton memcached bindings, like python-memcached. Then set the CACHE_BACKEND like this:

CACHE_BACKEND = 'memcached://<server-address>:<port>/'

where server address is usually localhost or 127.0.0.1, and the port 11211. But it can be anything else. Restart and enjoy :)

how much faster does it run? Anyone looked into the code to see what is being cached?

For me the slowest part of the SQL involved forum_node_tags table. Now they are gone to memcached. Page load times are now < 1 sec with 200K+ questions a decrease from ~30sec for a page.

Awesome. My site is super fast now with everything loads in under a sec. This is way better than the default caching. Installing memcached was easy as well.

The next major low hanging fruit are template loader caching and connection pooling. See:
