Build Identifier: HELIOS

bug 281871 is reproducedin HELIOS - fix is not complete

I am still facing this issue in latest HELIOS version.
My project also has large number of dependency libraries and jars.
I am okay for the computation to take long time, but the problem is that UI
hangs for this much time. 
In my opinion the real fix for this problem is to take out this computation
from the UI thread and do it in a different worker thread.
Also user should be provided with a progress indicator and an option to cancel
this computation.
In my understanding the optimizations alone wont scale.

Do you have Mylyn installed?

I am facing this bug in HELIOS 3.6.2. This bug appears only in computers that have a not-fast-enough cpu like Dual Core T4500 2.3GHz... Eclipse works smoothly with the same project on Core i5 computers.

Can you get us some thread dumps while content assist is taking some time?
