RAMcache

Architecture

privateSQL

Webserver

Filer

Store cache in /tmp

- /tmp is mount in RAM- Reduce latency to get data from filerzs- Can divide by two the load of the webpage

Store laravel cache in /tmp

$ vim config/cache.php…'file' => [       'driver' => 'file',       'path' => '/tmp',],

$ vim config/session.php…'files' => '/tmp',

$ vim config/view.php…'compiled' => '/tmp',

Another tips

- Use “cron” for asynchronous tasks- You can see all your logs in logs.clusterXXX.hosting.ovh.net- Use “boost” if you have previsible load peaks- Check external connexions from PHP (APIs like twitter...)
