I try to install memcached coz I've realized it solves many things. I have actually 3 askbot sites, one is the production environment and the other two are for development/testing purposes.
I'm hosted on Webfaction, in a plan with 256MB allowed memory. I read their instructions about memcached here and here which explain a lot but I still have questions coz I m new in python and django:
memcached -d -m memory -s ~/memcached.sock how much memory should I set?PYTHONPATH=$HOME/webapps/django_app/lib/python2.7/ easy_install-2.7 --install-dir=$HOME/webapps/django_app/lib/python2.7/ --script-dir=$HOME/webapps/django_app/bin/ python-memcached ?For the application it does not matter how much memory you assign to the memcached instance (or any other type of cache). If you give less - the application might appear a little slower and that will be all.
Give as much as you can without running out of available memory.
Django application requires between 30 and 40 megabytes per process (that memory for the process itself - cache is a separate issue), if internationalization is enabled (in askbot it is mandatory).
Regarding your setup - I would do development on your home computer. It does help to have identical setup for the staging instance, but if you feel you are limited in the amount of memory - you can have cache-less staging instance (using "dummy" cache backend). Also, you can try setting it up so that you use only one python process to conserve even more memory.
It could be that you have stale cache, to fix that, start django shell in the same virtual environment and clear the cache manually.
python manage.py shell #in the virtual env
#then in the shell type:
from django.core.cache import cache
cache.clear()
We might need to add a management command that does the same... Please try the command above.

I asked also in webfaction, but I still don't know how much memory should I give to memcached. Any suggestions I would really appreciate! Thank you! (webfaction post is here)
