title: PERFORMANCE: Symfony Cache in RAM disk a good idea?
body: <p>I'm running a Symfony 3 APP, on Apache 2.4 with PHP 7.3.
  <strong>Memcached, opcache and apcu are enabled</strong> and configured as per the performance guide of the Symfony documentation. So I thought I was all set up...</p>
  <p>But then I found this text:
  Symfony makes heavy use of a filesystem cache. By default, the cache is located in app/cache/ENV where ENV is the environment currently accessed.</p>
  <p>Which I interpret as the cache being stored in a directory on the FS (which is usually a hard drive), hence here's my question:</p>
  <p><strong>Would it be of any help to the Symfony application's performance if I was to run the cache directory in a RAM disk?</strong></p>
  <p>Thank you!</p>
  <p>PD: If you know of any good guide on how to improve Symfony's performance in relationship with the database from a SysAdmin/DevOps perspective, I would be very grateful if you could share a link with me.</p>
