Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

Is Jetty really comparable to Glassfish and JBoss? Isn't it more at the feature level of Tomcat? – Evan Jul 17 '09 at 1:52
I heard, that it is lightweight but full AS compatible! – Martin K. Jul 17 '09 at 7:36

I have heard good things about Resin as well. It has been a while since I've used JBoss, but at the time (>5 years) it was excellent. Hopefully support is better now since it's more mature and Red Hat supported.

I heard that Glassfish is the fastest server if you scale up to a big environment. This does it by grizzly.

Here are some performance stats.

We are using grizzly (without whole glassfish) for our custom file-sharing solution. We have 4gb/s bandwidth loaded per server with single Xeon 3570. – DukeLion May 22 '12 at 11:33

it's discussable how much open source it is - but also take a look at resin.
