Memcache has been up and operational on my production site http://goniseko.com for a few months now. After getting everything configured and memory limits where they should be, I noticed that I have a very consistent 70% / 30% hit to miss ratio.
How can I improve this?
Also, I noticed that this is pretty consistent across other Drupal 7 sites where I have memcache installed.
What is it about Drupal, Memcache, or a combination of the two that won't allow for this extra 30% to be stored in the cache bins? How can I figure out what these queries are, and what can I do to get them in the bins?
I am hoping this is similar to APC. I have that configured so that I have a 100% hit rate for this site. I would like to have Memcache that high, or at least higher than 70%. That's almost 1 out of 3 queries that have to hit the db.
