The best recommendation is to make sure you're using the Sun JDK and not the GCC-GCJ. That alone will constitute a large speed up. I imagine the ram disk will give basic speed-up. Can't attest to the others though, Eclipse runs more than fast enough here.
It just does? Try installing Eclipse from the Ubuntu repos, then download it from eclipse.org and run it with the Sun JVM and Sun JDK. Tell me it doesn't scream in comparison.

How does the Sun JDK significantly outperform the GCC-GCJ?
What do you mean by this? The gcj JIT is shit compared to the jdk, that's how.
GCJ is fairy slow.
