PHP OPcache
We strongly recommend you verify that PHP OPcache is enabled for performance reasons. The OPcache is enabled in many PHP distributions. To verify if it is installed, see our PHP documentation.
If you must install it separately, see the PHP OPcache documentation.
PHP settings
We recommend particular PHP configuration settings, such as memory_limit, that can avoid common problems when using Magento.
For more information, see Required PHP settings.
PHPUnit
PHPUnit (as a command-line tool) 9.0.0
RAM
Upgrading the Magento applications and extensions you obtain from Commerce Marketplaces and other sources can require up to 2GB of RAM. If you are using a system with less than 2GB of RAM, we recommend you create a swap file; otherwise, your upgrade might fail.
System dependencies
Magento requires the following system tools for some of its operations:
SSL
- A valid security certificate is required for HTTPS.
- Self-signed SSL certificates are not supported.
- Transport Layer Security (TLS) requirement – PayPal and
repo.magento.comboth require TLS 1.2 or later.
Supported browsers
Storefront and Admin:
- Microsoft Edge, latest and previous major version
- Firefox latest, latest and previous major version (any operating system)
- Chrome latest, latest and previous major version (any operating system)
