Test computer processing speed with a simple Python script

I want to make a simple script just to test the time that the computer takes to execute it. I already built it with PyQt and made a kinda loop using QTimer. Now i need the "make busy" part. What kind of commands can I use just to make the computer work a little so I can get the time it takes and compare with other computers?

Here is my code so you can understand better:

self.Tempo = QtCore.QTimer(None)
self.Cron = QtCore.QTime(0,0,0,0)

def begin():
    self.Tempo.singleShot(999, update)       
def update():
    if self.lcdNumber.value() == 10:
        #Here I want to make some processing stuff            
        self.Tempo.singleShot(999, update)
def finish():
    took = self.Cron.elapsed() / 1000
    print("took: {0} seconds" .format(str(took)))


You can do any complex calculation problem in a loop:

  • Calculate factorial for some big number (easy to implement)
  • Calculate chain SHA1 hash 100 000 times (very easy to implement)
  • Invert big matrix (no so easy to implement)
  • ...
  • etc.

Some of those problems use CPU (factorial, SHA1), some others - CPU and memory (matrix invert). So first you need to decide, which part of computer you want to benchmark.
