Subject	Re: [platform-swt-dev] Why Eclipse run slower in Mac OS X Tiger / Leopard ?

But, on other applications (java) it is not true. the performance is normal.
Problem exist on the Eclipse (SWT <=> COCOA / Carbon ).
The question is, Why  ? Ports SWT for Carbon or Cocoa is not better ? If i execute it on Java 5 32bits, it will run better ?

On Apple-java-list, the answer is: SWT is the problem !  I don't believe.

You might have better luck getting an answer on the java-dev mailing list from Apple.

One possible culprit is that Java 6 on the Mac is a 64-bit server VM and therefore not as optimized for fast startup or user interaction.

Performance on 64bit machines is (see sun java faq) about 10-20% lower. Reasons are widely documented throughout the internet so feel free to dig in.
