Node.js vs. PHP CLI server Performance test for HTTP server

Environment:

64-bit ubuntu14.04,i5-3230m
PHP5.4.31 with Zendopcache
Node.js 0.10.35

Node.js Test

var http = require (' http ');
Http.createserver (function (req, res) {
Res.writehead ({' Content-type ': ' Text/html;charset=utf-8 '});
Res.write (' <! DOCTYPE html>Res.end ();
}). Listen (8082, ' 127.0.0.1 ');

To run the program:

Node T.js

To view the system CPU idle rate:

SAR 1

Stress test, concurrent 100, complete 100,000 requests:

ab-c100-n100000 Http://127.0.0.1:8082/t.js

Memory from 11MB to 61MB, the system CPU idle rate 65%, RPS reached 6049.

PHP CLI Server Test

<?php header (' Content-type:text/html;charset=utf-8 ');?>
<! DOCTYPE html>

To run the program:

Php-s 127.0.0.1:8081-t./

To view the system CPU idle rate:

SAR 1

Stress test, concurrent 100, complete 100,000 requests:

ab-c100-n100000 http://127.0.0.1:8081/t.php
Memory from 19.6MB to 20.0MB, the system CPU idle rate 57%, RPS reached 11405.

When the Opcache is not turned on, the memory rises from 8.3MB to 9.0MB, the system CPU idle rate 57%,rps reaches 8851.

PHP swoole Test

<?php
$http = new Swoole_http_server ("0.0.0.0", 9501);
$http->set ([
' Worker_num ' => 5//Open 5 working processes
]);
$http->on (' request ', function (swoole_http_request $request, Swoole_http_response $response) {
$response->header (' Content-type ', ' text/html;charset=utf-8 ');
$response->end (' <! DOCTYPE html>});
$http->start ();

To run the program:

PHP swoole.php

To view the system CPU idle rate:

SAR 1

Stress test, concurrent 100, complete 200,000 requests:

ab-c100-n200000 http://127.0.0.1:9501/swoole.php

After the test memory occupancy reaches 117MB, System CPU idle rate 39%, RPS reach 19216.

Conclusion: Both Node.js and PHP CLI server are single process HTTP requests, but RPS PHP is almost node.js twice times the memory footprint of PHP is only 1/3 of Node.js. Node.js It is commendable that the system CPU idle rate is 8% higher than PHP. PHP swoole Application of multiple processes and multithreading, RPS near 20K, the full use of multi-core, so the CPU idle rate is the lowest of the three. In addition, although the HTTP protocol is not supported by PHP-FPM, the performance of processing PHP requests is no worse than that of the PHP CLI server, and PHP-FPM can enable multiple processes to take full advantage of multi-core.
