I'm no expert on Tkinter, so I'll only give you the results from my running
of the program:

I ran this in Xdarwin on an Apple G4 Powerbook w/ 512 M of RAM running OSX.
I ran the script alongside top to gauge cpu usage. CPU usage by the user
(me), because top spits usage down amongst system and user, during the
running of this script jumped from roughly 30% to a rough average of 75%
with 85% being the maximum amount I saw.

So I would have to concur that it is NOT your sytem that is causing the
problem. Something in the app is draining CPU cycles.

If I had to guess, and I definitely could be wrong, I would say your problem
may lie in this section:

def start(self):
    self.testMeterCanvas.create_arc(self.box, start = 0, extent = 180, fill
= "white")
    while 1:
      self.count = self.count + .1
      if self.count == 1000:
        self.count = 0
      self.testMeterCanvas.create_arc(self.box, start = 0, extent = 180,
fill = "white")
      self.x = 25 * math.sin(self.count) + 33
      self.y = -25 * math.fabs(math.cos(self.count)) + 33
      self.testMeterCanvas.create_line(33, 33, self.x, self.y, fill = "red")
      root.update()

Good Luck.
SA
