I find the glassfish gem to be the most performant of all — and I don’t need to war-up my app.
I also have some mongrel cluster stuff, but glassfish is simpler and just works.
Voila…blazing speed, can handle lots of traffic. Note that I am also cominging into apache from a dyndns name. So, whatever IP I have, I can go straight to execution on the glassfish gem and NO warring up! What could be easier deployment, or a faster execution?
It’s running fantasticly and performing like nothing I’ve seen before Completely stable memory, no wirings or anything bad for 5 days now.. (with several ab/htperf stresstests).
It’s always exciting to get good endorsements of our efforts in the GlassFish team
