This project provides representative performance measures across a wide field of web application frameworks. With much help from the community, coverage is quite broad and we are happy to broaden it further with contributions. The project presently includes frameworks on many languages including Go, Python, Java, Ruby, PHP, Clojure, Groovy, JavaScript, Erlang, Haskell, Scala, Lua, and C. The current tests exercise plaintext responses, JSON seralization, database reads and writes via the object-relational mapper (ORM), collections, sorting, server-side templates, and XSS counter-measures. Future tests will exercise other components and greater computation.

We ran our tests using two dedicated i7 2600k machines as well as two EC2 m1.large instances. Below you will find instructions on how to replicate our tests using either EC2 or your own dedicated machines.

###EC2 Instructions

Create two EC2 instances running Ubuntu Server 12.04.1 LTS 64-bit. We tested on m1.large instances, but feel free to experiment with different configurations. Give the instance that will act as the application server more then the default 8GB of disk capacity (we used 20GB).

When propmted to create a security group for the instances, here are the ports that you'll need to open.

• 22 (SSH)
• 8080 (Most of the tests run on 8080)
• 3306 (MySQL)
• 5432 (PostgreSQL)
• 9000 (Play Framework)
• 27017 (MongoDB)
• 3000 (yesod)
• 8000 (snap)
• 16969 (cpoll)

To coordinate the tests via scripting, the servers need to be able to work together. So once the instances are running, the first thing you'll want to do is copy your ssh key to the application server instance so that you can ssh between the two machines:

sftp -i path-to-pem-file ubuntu@server-instance-ip
put path-to-pem-file .ssh/
exit

Now ssh into the server instance and clone the latest from this repository (the scripts we use to run the tests expect that you'll clone the repository into your home directory):

ssh -i path-to-pem-file ubuntu@server-instance-ip
yes | sudo apt-get install git-core
git clone https://github.com/TechEmpower/FrameworkBenchmarks.git
cd FrameworkBenchmarks

Next, we're going to setup the servers with all the necessary software:

./run-tests.py -s server-private-ip -c client-private-ip -i path-to-pem --install-software --list-tests
source ~/.bash_profile
# For your first time through the tests, set the ulimit for open files
ulimit -n 8192
# Most software is installed automatically by the script, but running the mongo command below from 
# the install script was causing some errors. For now this needs to be run manually.
cd installs/jruby-rack && rvm jruby-1.7.4 do jruby -S bundle exec rake clean gem SKIP_SPECS=true
cd target && rvm jruby-1.7.4 do gem install jruby-rack-1.2.0.SNAPSHOT.gem
cd ../../..
cd installs && curl -sS https://getcomposer.org/installer | php -- --install-dir=bin
cd ..
sudo apt-get remove --purge openjdk-6-jre openjdk-6-jre-headless
mongo --host client-private-ip < config/create.js

Assuming the above finished without error, we're ready to start the test suite:

nohup ./run-tests.py -s server-private-ip -c client-private-ip -i path-to-pem --max-threads number-of-cores &

For the number-of-cores parameter, you will need to know your application server's core count. For example, Amazon EC2 large instances have 2 cores.

This script will run the full set of tests. Results of all the tests will output to ~/FrameworkBenchmarks/results/ec2/timestamp. If you use a different configuration than two m1.large instances, please use the --name option to name the results appropriately.

nohup ./run-tests.py -s server-private-ip -c client-private-ip -i path-to-pem --max-threads cores --name ec2-servertype-clienttype &

So if you were running an m1.large and an m1.medium, it would look like this:

nohup ./run-tests.py -s server-private-ip -c client-private-ip -i path-to-pem --max-threads cores --name ec2-m1.large-m1.medium &

This will allow us to differentiate results.

Be aware that on Large instances, if you include the slower frameworks (and they are included by default), the total runtime of a full suite of tests can be measured in days, not just hours. The EC2 bill isn't going to break the bank, but it's also not going to be chump change.

If you have two servers or workstations lying around, then you can install and run the tests on physical hardware. Please be aware that these setup instructions can overwrite software and settings, It's best to follow these instructions on clean hardware. We assume that both machines are running Ubuntu Server 12.04 64-bit.

Before you get started, there are a couple of steps you can take to make running the tests easier on yourself. Since the tests can run for several hours, it helps to set everything up so that once the tests are running, you can leave the machines unattended and don't need to be around to enter ssh or sudo passwords.

1. Setup an ssh key for the client machine
2. Edit your sudoers file so that you do not need to enter your password for sudo access

As it currently stands, the script that runs the tests makes some assumptions about where the code is placed, we assume that the FrameworkBenchmarks repository will be located in your home directory.

Check out the latest from github:

cd ~
git clone https://github.com/TechEmpower/FrameworkBenchmarks.git
cd FrameworkBenchmarks

Next, we're going to setup the servers with all the necessary software:

./run-tests.py -s server-ip -c client-ip -i path-to-ssh-key --install-software --list-tests
source ~/.bash_profile
# For your first time through the tests, set the ulimit for open files
# Most software is installed automatically by the script, but running the mongo command below from
# the install script was causing some errors. For now this needs to be run manually.
cd installs/jruby-rack && rvm jruby-1.7.4 do jruby -S bundle exec rake clean gem SKIP_SPECS=true
cd target && rvm jruby-1.7.4 do gem install jruby-rack-1.2.0.SNAPSHOT.gem
cd ../../..
cd installs && curl -sS https://getcomposer.org/installer | php -- --install-dir=bin
cd ..
sudo apt-get remove --purge openjdk-6-jre openjdk-6-jre-headless
mongo --host client-ip < config/create.js

Assuming this finished without error, we're ready to start the test suite:

nohup ./run-tests.py -s server-ip -c client-ip -i path-to-ssh-key --max-threads cores --name unique-machine-name &

This will run the full set of tests. Results of all the tests will output to ~/FrameworkBenchmarks/results/unique-machine-name/timestamp.

Server installation scripts for Windows Server 2012 R2 on Amazon EC2.

Instructions:

• Create an instance from the Microsoft Windows Server 2012 Base image on Amazon EC2
• Connect to it via Remote Desktop
• Copy installer-bootstrap.ps1 from this repo to the server (for files CTRL-C + CTRL-V works alright)
• Copy your client private key too while you're at it
• Right click on the installer script and select Run with PowerShell
• It will ask something, just hit enter
• It will install git and then launch installer.ps1 from the repo which will install everything else
• Installation shouldn't take more than 5 to 10 minutes
• Then you have a working console: try python, git, ssh, curl, node etc. everything works + PowerShell goodies

The client/database machine is still assumed to be a Linux box, you can install just the client software via

python run-tests.py -s server-ip -c client-ip -i "C:\Users\Administrator\Desktop\client.key" --install-software --install client --list-tests

Now you can run tests:

python run-tests.py -s server-ip -c client-ip -i "C:\Users\Administrator\Desktop\client.key" --max-threads 2 --duration 30 --sleep 5 --name win --test aspnet --type all

Server installation scripts for Windows Server 2012 with SQL Server 2012 Standard on Amazon EC2.

Instructions:

• Create an instance from the Windows Server 2012 RTM English 64-bit SQL 2012 Standard image on Amazon EC2
• Connect to it via Remote Desktop
• Run a Command Prompt as Administrator
• Enter powershell -ExecutionPolicy Bypass -Command "iex (New-Object Net.WebClient).DownloadString('https://raw.github.com/TechEmpower/FrameworkBenchmarks/master/setup-sqlserver-bootstrap.ps1')"
• This will configure SQL Server, the Windows Firewall, and populate the database.

Now, when running python run-tests.py, just add -d <ip of SQL Server instance>. This works for the (Windows Server-based) aspnet-sqlserver-raw and aspnet-sqlserver-entityframework tests.

After a test run, the directory ~/FrameworkBenchmarks/results/machine-name/timestamp will contains all the result files. In this folder are four files: three CSV files, one for each of the test types (json, db, query), and a single results.json file that contains all the results as well as some additional information. The results.json file is what we use to drive our blog post, and may or may not be useful to you. There are three subdirectories: one for each of the test types (json, db, query), each of these directories contain the raw weighttp results for each framework.

If you are making changes to any of the tests, or you simply want to verify a single test, you can run the script with the --test flag. For example, if you only wanted to run the JRuby tests:

nohup ./run-tests.py -s server-ip -c client-ip -i path-to-ssh-key --max-threads cores --name unique-machine-name --test rack-jruby sinatra-jruby rails-jruby

We hope that the community will help us in making these tests better, so if you'd like to make any changes to the tests we currently have, here are some things to keep in mind.

If you're updating a dependency of a framework that uses a dependency management system (Bundler, npm, etc.), please be specific with the version number that you are updating to.

Also, if you do change the dependency of any test, please update the README file for that test to reflect that change, we want to try and keep the README files as up to date as possible.

If you would like to update any of the software used, again, please be as specific as possible, while we still install some software via apt-get and don't specify a version, we would like to have as much control over the versions as possible.

The main file that installs all the software is in installer.py. It's broken up into two sections, server software and client software.

Additionally, it may be necessary to update the setup.py file in the framework's directory to use this new version.

If you update any software, please update the README files of any tests that use that software.

When adding a new framework or new test to an existing framework, please follow these steps:

• Update/add benchmark_config
• Update/add setup file
• When creating a database test, please use the MySQL table hello_world.World, or the MongoDB collection hello_world.world

There are three different tests that we currently run:

• JSON Response
• Database (single query)
• Database (multiple query)

The single query database test can be treated as a special case of the multiple query test with the query-count parameter set to 1.

This test needs to follow the following conventions:

• The message object should be instantiated as a new object for each request.
• The test should use a JSON serializer to render the newly instantiated object to JSON.
• Set the response Content-Type to application/json.
• The response should be {"message": "Hello, World!"}
• White space in the response does not matter.

Pseudo-code:

obj = { message : "Hello, World!" }
render json.encode(obj)

This test will:

• Access a database table or collection named "World" that is known to contain 10,000 rows/entries.
• Query for a single row from the table or collection using a randomly generated id (the ids range from 1 to 10,000).
• Set the response Content-Type to application/json.
• Serialize the row to JSON and send the resulting string as the response.

By convention, if the test does not use an ORM, and instead uses the raw database connectivity provided by the platform (e.g., JDBC), we append a "-raw" to the test name in the benchmark_config file. For example, "php-raw".

Pseudo-code:

random_id = random(1, 10000)
world = World.find(random_id)
render json.encode(world)

This test is very similar to the single query test, and in some cases it will be implemented using the same code. A URL parameter is made available to specify the number of queries to run per request. The response is a list of objects resulting from the queries for random rows.

Pseudo-code:

number_of_queries = get("queries")
worlds = []
for i = 0; i < number_of_queries; i++
    random_id = random(1, 10000)
    worlds[i] = World.find(random_id)
render json.encode(worlds)

The benchmark_config file is used by our run script to identify the available tests to be run. This file should exist at the root of the test directory. Here is its basic structure:

{
  "framework": "my-framework",
  "tests": [{
    "default": {
      "setup_file": "setup.py"
      "json_url": "/json",
      "db_url": "/db",
      "query_url": "/db?queries=",
      "port": 8080,
      "sort": 32
  }, {
    "alternative": {
      "setup_file": "alternate_setup.py"
      "json_url": "/json",
      "db_url": "/db",
      "query_url": "/db?queries=",
      "port": 8080,
      "sort": 33
    }
  }]
}

• framework: Specifies the framework name.
• tests: An array of tests that can be run for this framework. In most cases, this contains a single element for the "default" test, but additional tests can be specified.
  • setup_file: The location of the setup file that can start and stop the test. By convention this is just setup.py.
  • json_url (optional): The relative URL path to the JSON test
  • db_url (optional): The relative URL path to the database test
  • query_url (optional): The relative URL path to the variable query test. The URL must be set up so that an integer can be applied to the end of the url to specify the number of queries to run, i.e. /db?queries= or /db/
  • port: The port the server is listneing on
  • sort: The sort order. This is important for our own blog post which relies on consistent ordering of the frameworks. You can get the next available sort order by running: ./run-tests.py --next-sort

The setup file is responsible for starting and stopping the test. This script is responsible for (among other things):

• Setting the database host to the correct IP
• Compiling/packaging the code
• Starting the server
• Stopping the server

The setup file is a python file that contains a start() and a stop() function. Here is an example of Wicket's setup file.

import subprocess
import sys
import setup_util
