Wait a minute! I see a lot of cache expires and have been thnking it must be because of time. My app probably uses up a total of 1-3MB in cache per user (multiple caches per user).
So, suppose my app uses up 3 MB per user, you mean to say, at any point, I won't be able to serve more than 340 users!!
