A fresh install of Magento 2 slow on localhost? This can happen often especially on developer mode and indeed can be frustrating.

Working on production mode while developing in Magento 2 can be time consuming as you need to compile and deploy your static files any time you make updates to the templates, layout or add new dependencies to your classes.

Here are some steps you can take to make your Magento 2 faster on development mode.

Use latest PHP version

Use the latest available PHP version that is compatible with your Magento version to increase performance.

Install and enable PHP OPcache

Make sure you install and enable PHP OPcache. Also because you don’t want to clear the OPcache anytime you modify a PHP file so  to disable timestamp validation add the following line to your php.ini:

opcache.validate_timestamps = 0

Turn off Xdebug

Enable Xdebug only when you really need it because it requires a lot of memory and degrades performance.

For Magento the xdebug.max_nesting_level configuration needs to be set to 200 or greater. Also you can increase the memory available to PHP to get an increase in performance with Xdebug on.

Enable partial caches

In developer mode I found that all caches are disabled, but in your env.php you can set what caches you still want to use:

'cache_types' =>
      array (
        'config' => 1,
        'layout' => 0,
        'block_html' => 0,
        'collections' => 1,
        'reflection' => 1,
        'db_ddl' => 0,
        'eav' => 1,
        'customer_notification' => 1,
        'target_rule' => 1,
        'full_page' => 0,
        'config_integration' => 1,
        'config_integration_api' => 1,
        'translate' => 1,
        'config_webservice' => 1,
        'compiled_config' => 1,

Use Percona instead of MySQL

Another recommendation from Magento for your localhost is to replace your MySQL database with Percona.

Percona Server for MySQL® is a free, fully compatible, enhanced and open source drop-in replacement for any MySQL database. It provides superior performance, scalability and instrumentation.


As a wrap up for a Magento 2 slow on localhost:

  • Use latest PHP version
  • Install and enable PHP OPcache
  • Turn of Xdebug
  • Enable Partial caches
  • Use Percona instead of Mysql
