Performance
====================
Caching is all about performance, so I carefully track Dalli performance to ensure no regressions.
You can optionally use kgio to give Dalli a 10-20% performance boost: `gem install kgio`.
Note I've added some benchmarks over time to Dalli that the other libraries don't necessarily have.
