Concerning speed: As I am working with Java, too I would suggest to try NetBeans instead of Eclipse
Beans get me flatulences. But seriously, what's wrong with Eclipse's performance? I tried it on my aged hardware here not long ago and was surprised how very well it worked. It took about 5 seconds to start up, and one or two lage dialogs lagged a bit when opening, but that's pretty much it. I tried the C++ version too, which looked nice as well. But then, I didn't find the compiler option panel before my attention span ended, so I trashed it

Considering how much anything written in Java sucked 10 years ago (completely unusable), this was really stunning.
