High CPU doesn't start swap being used. If you start filling your RAM and the system needs more space then it will swap data in the RAM to the swap space then load the new application to RAM.

Not using swap is a good thing. It means that your system has enough RAM for it's use.

For more info about swap and paging, please read this:

Swap is only triggered by low memory situations, NOT by high CPU loads.
