The Great Web Framework Shootout


Welcome to the great web framework shootout. Here you will find test code and benchmark results comparing the performance of a few of the most popular F/OSS web frameworks in use today.

Please see The Great Web Framework Shootout's website for disclaimers, pretty little graphs, and other important information.

"Will you please add XYZ to the results?"

Maybe, if you can convince me that enough people would be interested in having it displayed next to heavyweights like Rails and Django. Fork the repository and submit a pull request with the test app code and your best sales pitch. Otherwise, I'd suggest you boot up the EC2 AMI and do your own benchmarking.

Benchmark Results

Three basic tests were set up for each framework up to run. Below are the results of each test in requests per second from highest (best performance) to lowest (worst performance).

The "Hello World" String Test

This test simply spits out a string response. There's no template or DB calls involved, so the level of processing should be minimal.

Framework Reqs/sec
web.go (Go r59) 3346
Pyramid 1.2 3026
Bottle 0.9.6 2825
Django 1.3.1 2159
Flask 0.7.2 2054
Sinatra 1.2.6 1583
CodeIgniter 2.0.3 929

Kohana 3.2.0 714
Rails 3.1 711
Symfony 2.0.1 273
CakePHP 1.3.11 254

The "Hello World" Template Test

This test prints out Lorem Ipsum via a template (thus engaging the framework's templating systems).

Bottle 0.9.6 2417
web.go (Go r59) 1959
Flask 0.7.2 1918

Yii 1.1.8 548
CakePHP 1.3.11 203
Symfony 2.0.1 171

The "Hello World" Template Test With DB Query

This test loads 5 rows of Lorem Ipsum from a SQLite DB (via the default ORM or a sqlite3 driver) and then prints them out through a template (thus engaging both the framework’s ORM/DB driver and the templating system).

Framework Reqs/sec
Bottle 0.9.6 1562
Flask 0.7.2 1191

Test Platform Setup

All tests were performed on Amazon's EC2 with the following configuration:

  • ami-fbbf7892 m1.large ubuntu-images-us/ubuntu-lucid-10.04-amd64-server- 20110719.manifest.xml
  • As a "Large" instance, Amazon describes the resources as: 7.5 GB of memory, 4 EC2 Compute Units (2 virtual cores with 2 EC2 Compute Units each), 850 GB of local instance storage, 64-bit platform.
  • Apache 2.2.14 was used. (Yes, I know there are other options, but with Apache's market share I figured it would be a good baseline.)
  • Python 2.6.5 and mod_wsgi 2.8 (embedded mode) were used for the Python based tests.
  • Ruby 1.9.2p290 and Phusion Passenger 3.0.9 were used for the Ruby based tests.
  • PHP 5.3.2 (with APC enabled) was used for the PHP based tests.
  • ApacheBench was run with -n 10000 and -c 10 about 5-10 times each, and the "best guess average" was chosen.

Most Recent Changes


  • Updated Ubuntu LTS AMI (ami-fbbf7892 ubuntu-images-us/ubuntu-lucid-10.04- amd64-server-20110719.manifest.xml)
  • Rails 2.x and 3.0 were dropped in favor of Rails 3.1.
  • CakePHP 1.2 was dropped in favor of 1.3, but Symfony and Yii were added as they seem to have considerable market share.
  • Corrected faulty configuration of CakePHP's caching engine.
