Impressed by JBoss AS7 book from PACKT, I decided to try out JBoss AS7 release.
The first thing I noticed is the startup time. JBoss AS7 book author claims it is fast to start due to the new modular architecture. I can see on his screenshot, that it is about 5 seconds (on my netbook it is 11 seconds). However, I personally do not consider it "that fast". Certainly, something like GlassFish would take longer.
