HotSpot vs. Jikes + performance tuning
I'm starting to run Tomcat 5.0.27 on a production server box. The question I have is as to which JVM to run it under. Last time I checked (a year ago) jikes was a lot faster, but then again things are in constant flux. Also, my production server (RedHat 9.0 on a Celeron 2.6GHz and 512MB of RAM) could not be set up with the latest version of Apache (don't ask - it's my hosting company) and so I'm serving static content under Tomcat as well. I expect there to be a lot of traffic on this site and maximizing resources is a MUST. ANY input would be appreciated.

RE: HotSpot vs. Jikes + performance tuning
Hi, I also haven't compared Jikes and javac in a while, but my impression is that JDK 1.4.2 made things very close to equal and even made javac faster sometimes.

Well, since you asked: 0/ test, test, test: that is, test load and functionality under various JVMs. See which one performs best, per your requirements. 1/ Tune, tune, tune: there's much more to performance than just the JDK. You'll also have to take heap, GC, etc into consideration. 2/ install this same JVM + configuration in production. Ideally, you'd have similar hardware in both your test and production environments, such that any tuning you do could be applied to both. Given what I see on the list, I get the impression most of the people here (or at least, most of the posters ;) use Sun's JVM. -but YYMV, and thus, you'd do yourself a favor to test it for yourself. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
