Hi Bill.

I have not made tests with graphs.

I have made test of perfomance exactly using different versions of JVM (since 1.3 up to 1.6). 

The test is inspired in the article of Matt Love in http://www.ddj.com/dept/java/188700760 (for example). 

I got resulted better (for the test indicated in the article) in a P4 with Windows XP 2.8Ghz with 1Gb of memory. 

My Mac is one iBook 1,2 with 768Mb of RAM with MAC X 10.4.7 

Some data are: 

Time of execution in the P4 for StringBuffer using JVM 1.3.1_17: 32 ms 

In the Mac with VM 1.3:20 ms 

Same execution now with VM 1.4.2_12: 

P4 - 16ms 

Mac - 17 ms 

Using VM 1.5.0_07: 

P4 - 9 ms! 

Mac - 26 ms! 

Finally with VM 1.6.0-rc-b90 

P4 - 5 ms 

Mac - 136 ms!   

If you if to interest I can send it the complete graphs that I generated. 

Thank´s

Carlos

Without more details regarding what the program does, it's difficult to
tell.

My company used to offer a product that did intensive signal processing
and drawing. Linux and Windows were faster because the level of graphics
they support by default was inferior. If we turned on anti-aliasing,
Linux and Windoze would produce higher qualitiy graphics...nearly
equivalent to that on OS X, but their performance became inferior,
whereas OS X remained unphased.

That's just one difference between OS X and Windoze/Linux. As far as OS
X to OSX issues go, I have noticed that Java 1.4.X on Panther gives me
the impression of being faster than the equivalent on Tiger, but I have
never verified this...it just 'seems' faster.

Hope this helps,

Bill Wagner
