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 important disclaimers and other detailed information about these benchmarks. If you have any questions or comments, feel free to contact me on Google+.

"Do these results have any real world value?"

Probably not. When it comes to code, the slightest adjustments have the potential to change things drastically. While I have tried to perform each test as fairly and accurately as possible, it would be foolish to consider these results as scientific in any way. It should also be noted that my goal here was not necessarily to figure out how fast each framework could perform at its most optimized configuration (although built-in caching and other performance tweaks were usually enabled if the default configuration permitted it), but rather to see what a minimal "out-of-the-box" experience would look like.

Additionally, nothing here is intended to make one web technology appear "better" than another. When it comes to using the right tool for the job, "faster" does not necessarily mean "better" (very few real world projects are going to depend solely on page request speeds).

"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 under the dev branch with a test app in the same format as the other tests, and make sure you include 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 to run. Below are the results of each test in requests per second from highest (best performance) to lowest (worst performance).

Remember: Comparing all of these framework tests side-by-side isn't really "fair" because they are all so different. Compiled languages (e.g. Go) are expected to be faster than scripted languages. Tests using an ORM (e.g. Rails, Django, Pyramid, etc.) are expected to be slower than tests using only a plain database library (e.g. Bottle, Flask, Sinatra, etc).

Please see the website for more detailed information and a better breakdown of the tests (graphs included!).

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
TG 2.1.2 839
Yii 1.1.8 726
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).

Framework Reqs/sec
Bottle 0.9.6 2417
web.go (Go r59) 1959
Flask 0.7.2 1918
Pyramid 1.2 1650
Sinatra 1.2.6 1329
Django 1.3.1 1005
CodeIgniter 2.0.3 884
Kohana 3.2.0 675
TG 2.1.2 663
Rails 3.1 625
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
Sinatra 1.2.6 982
web.go (Go r59) 741
Pyramid 1.2 555
CodeIgniter 2.0.3 542
Django 1.3.1 465
Rails 3.1 463
Kohana 3.2.0 423
TG 2.1.2 298
Yii 1.1.8 201
CakePHP 1.3.11 193
Symfony 2.0.1 113

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.
