A sample project to showcase a real world example and benchmarks for crowphp

CrowPHP Sample project

This project is to showcase an example of how a real world project might look like. It has two basic endpoints to show-case the raw performance like "hello world" and the other endpoint that needs to connect to database and fetch some data.

Requirements

1. PHP-CLI >8.0
2. PHP Swoole Extension

$ pecl install swoole

3. Composer Packages

$ composer install

4. MySQL server
5. Import the sample schema and data from db_schema/benchmark_db.sql (the schema looks like as follows)

CREATE TABLE `Users` (
  `userId` int(11) NOT NULL,
  `firstname` varchar(45) DEFAULT NULL,
  `lastname` varchar(45) DEFAULT NULL,
  `email` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`userId`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Note: We have a single table Users inside a database named benchmark that contains around 100 rows of random data. 6. Finally, adjust your MySQL details in src/Bootstrap.php

You can run the project as follows:

php server.php
$ Crow server listening on 0.0.0.0:5005

Endpoints

1. GET / This is a hello world example it simple returns Hello World
2. GET /users returns a list of users from database in the following format

[{"userId":0,"name":"Rhett Purdy","email":"[email protected]"}]

Benchmarking

I have used apache benchmark Version 2.3 <$Revision: 1843412 $> to run 20k requests with 30 concurrent calls on the GET /endpoint and 100k calls on GET /users, and here are the results

    99%      3
    100%     12 (longest request)

   This first test is trivial but, I still wanted to showcase the raw performance of the framework what this means is that the CrowPHP implementation adds almost no overhead for application.

   In this second result we can see that even with decent amount of data transfer the performance drop is not that much and if we look at our database the connections to the database stays steadily at 12 connections where if we were not using connection pooling we would have a lot more connections to database.
