Application slow on Mac

Hello,

I am new to the Macintosh environment and was wondering if someone could help me here.

I have written a java application (stand-alone) on a Windows platform. The application is computation intensive and uses Java3D APIs to render 3D objects. Also, the application uses JSci APIs to render 2D graphs and has a number of other features, which use extremely large arrays. The application is built using Swing APIs whereever possible.

Now, when I run the application (jar) on a Windows platform (XP), it runs fine as expected. However, when I run the same application on Mac OS X (10.3.5), it runs extremely slow, takes ages to render 3D objects or to do anything as a matter a fact.

In summary, the application runs much much faster on Windows (Intel P4 - 1.4 GHz, 768MB RAM) as compared to running it on a Dual 1.42 GHz PowerPC G4 with 1GB RAM. This does not make sense to me.

Any insight/help would be highly appreciated.

Thanks in advance.

Do you have the most up-to-date Java imaging library? I recall having to download and install an update for a graphics app I was using.

Yes, I have the latest Java3D and JAI library installed on my Mac. As a matter of fact, problem exists with the entire application and not just the graphics rendering.

Any other thoughts?

Thanks.

The use of Java3D on the Mac is news to me. I have read that Apple chose not to support the Java3D extension.

Is this the reason it does not work?

If it is support now, that would be great
