Maatkit Now Supports Memcached | MySQL Performance Blog

Have you ever wondered how optimized your Memcached installation is? There is a common misconception that one doesn't have to think too deeply about Memcached performance, but that is not true. If your setup is inefficient, you could:

* Burn Memory
* Waste Network Round-Trips
* Store Keys That Never Get Retrieved
* Have a Low Cache Hit Ratio (i.e. query MySQL too much)
* Suffer a fate too horrible to contemplate.

Percona does a lot of consulting around Memcached, so we try to take a quantitative, scientific approach to measuring memcached performance, just like everything else we do.
