After working on a large App Server Project... (Score 1)

OK, here's the scoop. I *DO* servlet programming for a living. We've pulled together webmacro, IBM WebSphere AppServer and MySQL on Linux. But if I had a choice, I wouldn't be using IBM WebSphere. We got lucky, and didn't have to pay for it. It's mostly fast, and does everything we need it to - for now. But it's got it's flaws, and it's a resource pig - 30Meg of Memory to run two servlets? And It's the only app I've seen to Max out CPU Utilization on Linux. Hell, it's the only thing I've seen *KILL* apache deader than a doornail. We're still looking at the OpenSource Servers because they look smaller, faster, and just as feature rich. Please Tell me which one you choose, and why. I want to take it to my boss as an alternative.
