[CLOSED] Difference in speed in serato changing from CDJ900 to CDJ 2000'S

I recently changed from a pair of CDJ900 's to 2000'S,  I'm using serato in my setup.  When I had the 900' s they worked flawlessly whither the program now that I have my 2000'S hooked up (via HID) there seems to be Quite a bit of lag,  for example when scrolling for tracks via the robots knob there is a delay also I seem to be having a harder time beat matching when the other players were extremely easy and accurate.  My laptop is around 4 years and could be ready for replacement. Could it be that the CDJ 2000'S use up more memory due to the extra features?
