Which Open Source Java Application Server is the fastest?

  • Glassfish
  • Jetty
  • JBoss


  • Is Jetty really comparable to Glassfish and JBoss? Isn't it more at the feature level of Tomcat?

  • I heard, that it is lightweight but full AS compatible!

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.

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