Heartbeat

Heartbeat helps with:

slow file reads on cloud hostings where cache is not on the same storage as application (Azure);
slow file includes from composer;

Heartbeat finds all the files in your application, includes and "cache" warms

Best performance calling Heartbeat every 5 minutes having application + vendors under 20 000 files

composer require gundars/heartbeat ~0.1

> php vendor/gundars/heartbeat/load.php

Scanning /var/www/public/zend/approot
10102 files loaded in: 0h 2m 49s

Paste this code in your index.php:

use Heartbeat\Heartbeat;

if (array_key_exists('heartbeat', $_REQUEST)) {
    $heartBeat = new Heartbeat();
    $heartBeat->load(__DIR__);
}

and call via http(s) http://example.com/?heartbeat=true

<?php

use Heartbeat\Heartbeat;

$heartBeat = new Heartbeat();
$heartBeat->->load(__DIR__ . '/../../../');

Prints all included files

$heartBeat->verbose()->load(__DIR__);

stops script execution after file include is finished

$heartBeat->verbose()->load(__DIR__, true);
