Comparative Cache Performance Numbers
Some guys have created a java cache test tool called cache4j_perfomance_tester.The results for ehcache-1.1 and ehcache-1.2 follow.
According to their test methodology both versions of ehcache are the fastest for all three scenarios. Compared with oscache, ehcache was 4 times faster for two of the scenarios and twice as fast for one.
I find these results interesting. I had the JCS guy Aaron Smuts complaining about the old performance numbers I had up for JCS. They were quite old so I removed them. I didn't have the time to do my own analysis but I am happy that someone else has. Ehcache is in good shape.
