I have a single page app (Rails + Backbone.js + Postgres on Heroku), and as some of my queries are starting to slow down for users with lots of data (there are multiple queries per object), I want to start caching the JSON I'm sending the client.
I'm already using Redis with Resque, so I'm not sure if I should be using the same redis instance for both Resque and general data caching. Is that a reason to go with Memcached?
I guess I'm looking for general input from those with experience with either so I can quickly decide on one of the two and start caching stuff (sorry if a clear-cut answer cannot be given).
Thanks for any help.
