Changed session store from ActiveRecord, deleted sessions table and now...

Is there any chance that changing the session store from ActiveRecord to cookies, and deleting the sessions table could cause performance problems with my app? Everything was running fine until I made that change (and added indexing to all my tables). Now the app jumps right into the swap and chows up all the memory rendering the server useless in a matter of hours.

I went through all my recent commits to see what the possible culprits might be and this was the only thing that raised a question. Thoughts?

Yay!!

Sure, make one major change at a time. :slight_smile:

Failing that -- did you have any kind of performance analysis going on before? NewRelic, etc.? Why did you "add indexing"? What are you doing now to determine where the bottleneck is?
