JIT-optimized version of Eclipse?

I am not happy with the speed Eclipse runs inside my Windows XP VM (in VMWare). Do you know whether there is a JIT-optimized version of Eclipse that runs faster then the officially distributed one?

Update: Thank you @PterT, @Jörg and @maarons for pointing out my misconception. I am new to Java and so some terms may be still not very clear to me. In a recent question I asked about a CPU optim开发者_运维问答ized for Java, one of the answers was that such CPU is not needed because

Every commonly used JVM has a sophisticated JIT compiler than intelligently native-compiles methods that would benefit from it. So nowadays executing bytecode natively is fairly useless.

Since I am new to Java, I thought perhaps I missed something important that makes it less CPU-hog than I currently experience. Are you saying that the only way to make Eclipse snappy is by running it on real hardware instead of inside a VM?

This question just doesn't make sense as JIT compilation is a property of JRE, not Eclipse. You could try Zero and Shark enabled Icedtea, but I don't think it will be faster - your problem is probably running a resource eating application like Eclipse in a limited environment like a virtual machine. Try running it without the virtualization layer if you need more speed.

Your question doesn't make sense. It is simply impossible to download a JIT-optimized version of Eclipse, since the very definition of "JIT-optimized" is "optimized at runtime".

Give it more memory. XP needs at least 1Gb for Eclipse to run well for any non-trivial load.
