I'm running Eclipse on Ubuntu (x64) on OpenJDK and it works fine. My hardware isn't particularly fast either. I might reboot one a week or so. I do have 8GB of memory though.

For some reason, on Ubuntu x86, Eclipse is really slow for me.

IntelliJ Idea is much better. And now the community edition comes with capabilities for Android projects.

I recommend it instead of Eclipse.
