Step 2: Check OPcache parameters

# php -i | grep opcache

A few notable parameters

  • opcache.interned_strings_buffer: The amount of memory used to store the interlaced strings, in megabytes. This configuration directive is ignored in PHP < 5.3.0. But we're using newer PHP so we'll need this configuration. The default value in Cyber ​​Panel is “8”.
  • opcache.max_accelerated_files: The maximum number of scripts that OPCache can cache. The minimum value is 200. The maximum value is 100000 in PHP < 5.5.6 and 1000000 in later versions. The default value in Cyber ​​Panel is “4000”.

opcache.memory_consumption: Size of RAM allocated to OPcache for use, in Megabytes. The default value in Cyber ​​Panel is "32".
