My last eclipse -O2 attempt was a few weeks ago, and some fixes have 
gone in to GCJ since then. At this point it should be possible to 
compile most of the .jar's with -O2, but there are likely to still be 
optimization bugs that cause eclipse to misbehave or crash when it is 
built with -O2. Is resources.jar still used entirely uncompiled? We 
should perhaps concentrate on that bug first.

Startup time is also an issue - we should be able to beat the JVM easily 
here but currently we arn't. It would be worth profiling the startup 
sequence to see if any obvious bottlenecks can be identified.
