Timing django/python function calls

Doing some optimization for SWITCH.co.il I've come across a handy snippet to time the execution of python/django functions. Since I was doing deep-dive checking I also wanted to know the stack of the executed function. Figured someone (me) would want to use it in the future, so I'm adding it here. Not the prettiest of code, but it works.

import time
import inspect                                                
def timeme(method):
    def time_wrapper(*args, **kw):
        startTime = int(round(time.time() * 1000))
        result = method(*args, **kw)
        endTime = int(round(time.time() * 1000))
        stack=[]  
        for i in inspect.stack():
            if i[3] == 'time_wrapper': continue 
            stack.append(i[3])
        print 'Time(ms): ', ('%04d')%(endTime - startTime), method.__name__, u'->' ,u'->'.join(reversed(stack[0:5]))
        #only show 5 top stack
        return result
    return time_wrapper

#usage example
@timeme
def some_function(x,y):
    do_something
    return something
