How to test server speed with Python

Question

I'm trying to test the speed of my servers, and compare it with third parties' servers including Facebook, Tumblr and Google. I need to build a report with at least 100's of requests and I decided to do this with Python.

The idea is that I upload an image to Facebook, then re-download it (as Facebook modifies the image I upload) and upload it to the other third party servers as well as my own. I request the file x times for each server, and Python will print the time the request took each time.

Here is my script:

from time import time
from urllib import urlopen

# vars
url = raw_input("Please enter the URL you want to test: ")

for i in range(0,100):
    start_time = time()
    pic = urlopen(url)

    if pic.getcode() == 200:
        delta_time = time() - start_time
        print "%d" % (delta_time * 100)
    else:
        print "error"
print "%d requests made. File size: %d B" % (i, len(pic.read()))

I'm not great at Python so I'm not sure if I'm doing this right.

Is this the best way to do this?

If the code works the way it should, then, strictly speaking, the question is a little off-topic here; there's a site called Code Review where you can post working code for review. — Lev Levitsky

There are scores of HTTP performance testing tools available. I would suggest you try one of those before creating your own.

Can I use this to test third party servers? I need to compare my download times to that of Facebook, Tumblr, Google, etc

If you go and hammer someone else's server, they might consider it a DoS attack and blacklist you, or take legal action. Besides, your server will never be faster than your internet connection. And I suspect Google and Facebook can afford a bigger "pipe" than most of us.

As pointed out by Lev Levitsky, this question actually belongs over at Code Review. The code I originally posted as intended, all I'm looking for is guidance on how to improve it.

Here is this question on Code Review.
