SQL query you are using is very simple and doesn't represent real world situations when you want to use caching. MySQL perfomance for record lookup by primary key is very good especially since you are connecting to database via unix socket missing networking layer. No surprise it beats FileCache and MemoryCache which have additional logic that deals with cached data expiration (BTW I bet you can get better perfomance by tuning data expiration settings).

In real world normally you need to cache only results of complex queries. Also you may want you caching code to handle data expiration, support caching of big data that you cannot fit in RAM, support cache shared by several processes, etc. When you need all these features in your caching code it is time to consider using something like Cache::Cache.
