Eclipse PDT 64Bit Windows 7 problem

This was the first thing that I thought is happening - my PDT IDE is working too slow because of incompatibility with my 64bit OS. I was 100% sure... because PDT "ate" ~80-100% of one of my 4 CPUs. I hate these moments thinking that my QuatroCore SUCKS runing java app :( ... Thanks Lord I was wrong.

Just turn the Outline view OFF and CPU back to 10-20%... too many classes , methods, properties are killing Outline view in Eclipse PDT. Don't keep it constantly open.
