Hello,
I had the same problem a while ago with my trackpad. It turned out the smart gesture software installed in the laptop was causing the slow response from my trackpad, and I had to disable some of its features. Sounds like you might be having the same issue.
To disable some of the features of the Smart Gesture software, you simply go to the device settings and uncheck all of the gestures.
