Yeah, I gave some thought to this a while back (but didn't actually do it) ... The issue is that EOF's problem is not that it's CPU or memory bound, its problem is that it is a single-lock basically non- concurrent architecture. Distributing it with Terracotta just causes MORE lock contention on a single EOF stack. The only way to scale with EOF is by having multiple stacks, whether that is in a single instance or across multiple instances, and Terracotta doesn't really have much to offer you at that point, so I never went any further with it. Using it for the appserver layer is potentially interestesting, but it's hard to get classloader separation within WO to be able to set it up properly.

Has anyone done any investigation into using Terracotta with EOF?

I didn't find anything but wanted to make sure before I dig in.
