Try using "setTimeout" instead of "setInterval". If your computer
cannot service interrupts quickly enough, you may be producing a flood
of interrupts.
For a simple example, see:

CPU speed determines the pace. It is also a good idea to use
"clearTimeout" or "clearInterval" to discard unserviced interrupts.
