Reply to Laptop cannot Handle Running Traktor Pro 2.6

Computer Specs:

HD: 500GB

DJ Equipment:
Numark Mixtrack
Traktor 2.6

I recently updated my Traktor program to the new 2.6 and I have been having issues running my DJ software without it freezing. It works fine when playing songs on both decks, but when it comes to transitions, adding effects, and recording mixes my laptop freezes for a few seconds and this usually happens every 10-15min. I originally had 4GB of ram and figured I would upgrade to 8GB hoping to fix the issue. I noticed the computer runs alot quicker, but when it comes to Traktor I still have the same issue. The CPU bar is consistently at 75% while playing songs through Trakor, and hits 100% quite frequently and causes it to freeze. Is there anything I can do to resolve this issue to improve the performance of my laptop or change settings in Traktor, let me know. Is this a common occurrence when using a Dell?
