When I bounce the whole session it takes way too long , this has not ever happened before, I use a fair amount of plug ins but I don't get it, it keeps on processing audio data and takes way to long. Should I optimize the pc? how do I do it? thanks guys. 

windows 7, 8ram, sonar x1 d.

I think "way too long" is a little vague. 
Do you mean, an hour for 3 tracks?

Why are you bouncing? What are you trying to achieve?
