Vs. EHCache

Hi, I realize this is kind of like an apples vs. oranges comparison, but I would be interested if you have any performance information vs. something like ehcache with a persistent store.

I'm currently evaluating for a simple schema to persist only 1 or 2 types of entities (but possibly 10k-100k instances) with simple index based queries which imagine both products could probably solve.

Unfortunately we don't have such information.

But if you don't need transactions, lock management, durability and recovery, advanced queries, etc.  - maybe the fastest solution is to use memory-based HashMap with serialization file as a persistence back end.
