<oremj> https://addons.mozilla.org/en-US/admin/models/
<oremj> pageload time is 10s for some reason

oremj:  page load time can be long for me on my dev server without memcache, but the second load is nice and fast.  We're sure memcache is on, right?*

I also ask because preview doesn't seem slow.  Is there anything else different between the two?

Comment 2

[Jeremy Orem [:oremj]]

I configured memcache. Is there a way to test if it is working? I can get the servers via the command line and they are the same ones remora is using.

Comment 3

[Jeff Balogh (:jbalogh)]

From the command line:

python manage.py shell

from addons.models import Addon
a = Addon.objects.get(id=1865)
print a.from_cache
a = Addon.objects.get(id=1865)
print a.from_cache

fail: I typoed a s/83/81/ in the CACHE_BACKEND, so it really wasn't working.

09:38 < clouserw> I'm writing a django equivalent to https://addons.mozilla.org/services/monitor.php

That should help stuff like this in the future.
