Apakah Swoole itu? Swoole adalah sebuah extension PHP yang memungkinkan progammer PHP menulis sebuah code yang high-performance, scalable, concurent, dan asyncronous. Baik itu TCP, UDP, Unix Socket, HTTP1, HTTP2 dan Websocket.
Secara sederhana, bisa dibilang, Swoole adalah jawaban
hinaan dari komunitas NodeJS yang mencari kemampuan asyncronous dan scalable di PHP.
Contoh HTTP Server bawaan Swoole:
[sourcecode language="php"]
<?php
$http = new swoole_http_server("127.0.0.1", 9501);
$http->on("start", function ($server) {
echo "Swoole http server is started at http://127.0.0.1:9501\n";
});
$http->on("request", function ($request, $response) {
$response->header("Content-Type", "text/plain");
$response->end("Hello World\n");
});
$http->start();
[/sourcecode]
kemudian contoh Swoole Websocket:
[sourcecode language="php"]
<?php
$server = new swoole_websocket_server("127.0.0.1", 9502);
$server->on('open', function($server, $req) {
echo "connection open: {$req->fd}\n";
});
$server->on('message', function($server, $frame) {
echo "received message: {$frame->data}\n";
$server->push($frame->fd, json_encode(["hello", "world"]));
});
$server->on('close', function($server, $fd) {
echo "connection close: {$fd}\n";
});
$server->start();
[/sourcecode]
dan contoh asyncronous task:
[sourcecode language="php"]
<?php
$server = new swoole_server("127.0.0.1", 9502);
$server->set(array('task_worker_num' => 4));
$server->on('receive', function($server, $fd, $from_id, $data) {
$task_id = $server->task("Async");
echo "Dispath AsyncTask: [id=$task_id]\n";
});
$server->on('task', function ($server, $task_id, $from_id, $data) {
echo "New AsyncTask[id=$task_id]\n";
$server->finish("$data -> OK");
});
$server->on('finish', function ($server, $task_id, $data) {
echo "AsyncTask[$task_id] finished: {$data}\n";
});
$server->start();
[/sourcecode]
Hasil Benchmark Swoole
Klaim lebih cepat dibanding setup PHP biasa, baik menggunakan Apache maupun NGINX/PHP-FPM, bisa dilihat dan dicoba sendiri dari repo Github:

Contoh hasilnya:
a. PHP + Swoole
Running 10s test @ http://127.0.0.1:1337/
4 threads and 400 connections
Thread Stats Avg Stdev Max +/- Stdev
Latency 7.02ms 6.94ms 82.86ms 85.27%
Req/Sec 827.17 552.85 2.38k 66.54%
22543 requests in 10.07s, 3.61MB read
Socket errors: connect 151, read 22680, write 86, timeout 0
Requests/sec: 2238.19
Transfer/sec: 367.20KB
dan jika dengan NodeJS:
Running 10s test @ http://127.0.0.1:1337/
4 threads and 400 connections
Thread Stats Avg Stdev Max +/- Stdev
Latency 20.34ms 4.50ms 125.04ms 97.89%
Req/Sec 3.09k 1.93k 6.06k 55.00%
122838 requests in 10.02s, 23.66MB read
Socket errors: connect 151, read 69, write 73, timeout 0
Requests/sec: 12263.37
Transfer/sec: 2.36MB
