Performance of Flask, Tornado, GEvent, and their combinations

Wensheng Wang, 10/1/11

Source: http://blog.wensheng.org/2011/10/performance-of-flask-tornado-gevent-and.html

When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:

1, Pure Flask (pure_flask.py)

Tools

Located in alphabetical order (not prefer)

ab – slow and single threaded, written in C
apib – most of the features of ApacheBench (ab), also designed as a more modern replacement, written in C
autocannon – fast HTTP/1.1 benchmarking tool written in Node.js
baloo – Expressive end-to-end HTTP API testing made easy, written in Go (golang)

	// Update the appropriate href query string parameter
	function paramReplace(name, string, value) {
	// Find the param with regex
	// Grab the first character in the returned string (should be ? or &)
	// Replace our href string with our new value, passing on the name and delimeter
	var re = new RegExp("[\\?&]" + name + "=([^&#]*)"),
	delimeter = re.exec(string)[0].charAt(0),
	newString = string.replace(re, delimeter + name + "=" + value);

	return newString;
