I think start time depends a lot upon your webapp(s). For instance, our
dev server is a virtualized quad-core 3.4GHz Xeon (or maybe it's a
dual-core with hyperthreading) that we share with who knows how many
other VMs. Tomcat 6.0.32 starts up in 6569 and that includes launching
our webapp which grabs ~4300 text mathematical expressions from our
database and parses them into evaluable objects.

I'd bet that Tomcat with no webapps deployed would start up in about 2
seconds on my hardware.

GlassFish didn't support AJP before? That doesn't seem right...
