Solve the following python programming problem given the following code:
def _check_speed(time_per_run, number = 4, run_warm = True) : 
    ' Speed checks should typically be very tolerant. Some machines are
        faster than others, but the tests should still pass. These tests are
        here to assure that certain effects that kill jedi performance are not
        reintroduced to Jedi.' 
    def decorated(func) : 
        @ functools.wraps (func) 
        def wrapper(self) : 
            if run_warm : 
                func (self) 
first = time.time () 
            for i in range (number) : 
                func (self) 
single_time = ((time.time () - first) / number) 
            print ('
speed', func, single_time) 
            assert (single_time < time_per_run) 
return wrapper
