J2SE 5.0 Performance White Paper
By Angsuman Chakraborty, Gaea News NetworkSaturday, May 14, 2005
Sun published performance benchmark for JDK 5.0. It is around 3 times faster than 1.4.2 as per Specjbb2000, less spectacular in other benchmarks. Read it.
In addition a different way of tuning the heap has been added for the throughput garbage collector. This new tuning allows the user to specify performance and memory utilization criteria to dynamically tune the sizes of the heap. This “self tuning” behavior is referred to in this document as “ergonomics”. For more on ergonomics please see the Ergonomics in the 5.0 Java Virtual Machine document.

Hi There, Cool. On the server side, for an untuned JVM, we saw quite a bit of performance improvement over JDK 1.4.2_04. More people need to be aware of these tuning settings. A good way might be for sun(and other app server vendors, like Apache) to bundle with a JVM tuned according to the operating system (for a given application(like portal)) BR, |
