Also, I think he made some other core tweaks too. But yeah, it's a huge difference. I've used the ehcache API directly too, about 9 months ago. It's not too bad at all. Take another look.

Will have to check it out..I tried to put in Ehcache a while back but couldn't figure out from the docs etc. (in the time i had) whether it was using SoftReferences - so I had abandoned it and quickly wrote my own which has been working great untouched for the longest time. I will have to compare Echache's performance with my CacheManager .. those numbers seem way too good to not switch over. Where do u think those kind of performance gains came from? - better concurrency and/or better hashmap alogrithm? both seem like a tight squeeze for further performance improvements. Nice..tip.
