I have just spent a little time comparing the performace of Orion
compared to JBoss with the Embedded Tomcat module:
The great news is that I can take the exact same ear file and deploy it
in both JBoss/Tomcat and Orion with no mods at all. (J2EE really does
show promise !!)
The not so great news is that Orion is noticebly faster. I didn't do
anything detailed in analysis but Orion was definitely faster at
delivering the pages back to the browser. On looking at Memory usage
(Just what win2k reported) they seemed the same but the interesting
thing was the number of threads used. Orion seems to resuse threads alot
more than JBoss/Tomcat combined. Now this may be configurable and so the
test really might not be fair. I know that some of the pooling stuff can
be set up for Tomcat pretty easily. I just thought people might be
interested in some basic observations. The thing that really seems to
let Tomcat down is how long it takes to compile jsps. Orion beats its
ass. Pre-compilation should solve that though.
