NSCache is slow
Really slow according to Shark:
Apparently inserting an object into NSCache is 50x slower than a regular NSMutableDictionary! It’s possible Shark might not be reporting the figures accurately.
My current work-around is to store up additions to the NSCache so that they can be inserted at a later time, when processing power is at less of a premium. Yes, shoot me. I’ve subclassed NSCache.
