In 4.3.x, our out of the box Glassfish bundle was over 220 megs and only worked on Windows.

In 4.4.x, with the help of Raju from Sun, we were able to create bundles for Glassfish around 135 megs in size. It provides a full JEE stack. I'm actually quite impressed with the speed and the GUI console from Glassfish. All in all, I think it's a pretty good replacement for WebLogic AS because of its enterprise features.

Glassfish itself still has some things to improve on (such as being able to migrate where you installed it to without running another ant task, something you can do easily in Tomcat but not in Glassfish).

On another positive note, while testing Glassfish and Geronimo, we found the performance to be several times faster. For some odd reason, the Geronimo jspc just crawled and would need to be recompiled on every restart.
