Redis and Memcache or just Redis?

Question

I\'m using memcached for some caching in my Rails 3 app through the simple Rails.cache interface and now I\'d like to do some background job processing with red

Answer 1

I don't know what you're using them for, but actually using both may give you a performance advantage: Memcached has far better performance running across multiple cores than Redis, so caching the most important data with Memcached and keeping the rest in Redis, taking advantage of its capabilities as database, could increase performance.
