In this release we have modified some PHP OPcache configuration settings to improve
speed of certain PHP operations. The new values match the recommendations from
the Magento 2 performance optimization guide.
Changes:
- OPcache for the CLI is now enabled (unless using PHP 7.0/7.1 in combination with
the Ioncube extension). - The OPcache memory size has been increased from a static 64MB to a dynamic value
ranging between 32MB and 512MB, depending on the node size. - The interned strings buffer size has been increased slightly for nodes with memory
sizes between 1GB and 30GB.
