That's z2.py -i:

  -i n

    Set the interpreter check interval. This integer value
    determines how often the interpreter checks for periodic things
    such as thread switches and signal handlers. The Zope default
    is 120, but you may want to experiment with other values that
    may increase performance in your particular environment.

Increase or decrease the number n and play with ab or some other load
testing tool....
