Is eclipse 3.2 optimzed to winXP?

I have both eclipse 3.2 installed for winXP and Ubuntu and it impossible
(very slow performace) to work with in Ubuntu compared to when I use it in
winXP (boths OS are installed on the same computer).

I am considering to downgrade to 3.1 or 3.0 when I use it in Ubuntu but
would like to know if eclipse is not really designed to run under linux.

In my experience with using Eclipse 3.2 under Ubuntu (and I'm assuming
you're using Dapper Drake) is not Eclipse's optimization but instead
rather the inefficiency of Sun Java under Ubuntu and other Linux
Distributions. An alternative Java Virtual Machine to Sun's Java is
Blackdown Java. While working with Blackdown Java will increase
performance while under Linux, There is no support to my knowledge of
developing or using Blackdown Java with Eclipse. However I myself have
had no issues so far with using Blackdown, there are certainly
differences between the two JVMs.

eclipse 3.1 was faster and I used the same sun jsdk, so something has
changed in 3.2 - eventhough it works fine in winXP

In my own experience, the default JVM on Ubuntu is not Sun's, but GCJ,
which has a really bad performance compared to Sun's (and probably IBM's).

So you should install Sun or IBM Java, and launch Eclipse with the -vm
argument.

Setting JAVA_HOME in the environment before launching eclipse, should
also do the trick.
