      opcache.enable=1
opcache.revalidate_freq=0
opcache.validate_timestamps=1
opcache.max_accelerated_files=65407
opcache.memory_consumption=400
opcache.interned_strings_buffer=16
opcache.fast_shutdown=0
opcache.use_cwd=1
opcache.save_comments=1
opcache.enable_file_override=1
opcache.max_wasted_percentage=10

    • For better server performances, it's recommended to fine-tune some variables:

      opcache.memory_consumption (default "64") MB, adjust to your needs, up to a quarter of total server's memory
      The OPcache shared memory storage size. The amount of memory for storing precompiled PHP code in Mbytes.

      opcache.max_accelerated_files (default "2000")
      The maximum number of keys (scripts) in the OPcache hash table.
      The number is actually the first one in the following set of "PRIME NUMBERS" that is bigger than the one supplied:
      { 223, 463, 983, 1979, 3907, 7963, 16229, 32531, 65407, 130987, 262237, 524521, 1048793 }…
      Only numbers between 200 and 1000000 are allowed.

      opcache.fast_shutdown (default "0")
      If enabled, a fast shutdown sequence is used for the accelerated code.
      The fast shutdown sequence doesn't free each allocated block, but lets the Zend Engine Memory Manager do the work.
      With opcache.fast_shutdown=1 in some case you can get this error: 500 Internal Server Error. Mostly on WIN IIS…

      NOTE ***Read Matias note***
      (use opcache.revalidate_freq=0 or updates in joomla fail)

      Because most of server's php scrips will now be served thru FAST MEMORY, all other HTML only website's will gain in speed.
      Reason : OPcache will free access to your HD, so mostly, ALL YOUR WEBSITES will run at least 200% faster…
      …and your server LOAD average will drop.

      Some OPcache GUI exist to help you visualize your caches and refine your config on GitHub:
      PeeHaa
      amnuts
      rlerdorf

      A more robust Setup config for live server with more than 150 clients:
      opcache.enable=1
opcache.revalidate_freq=0
opcache.validate_timestamps=1
opcache.max_accelerated_files=65407
opcache.memory_consumption=1024
opcache.interned_strings_buffer=32
opcache.fast_shutdown=0
opcache.use_cwd=1
opcache.save_comments=1
opcache.enable_file_override=1
opcache.max_wasted_percentage=10
opcache.revalidate_path=1

      On a WINDOWS IIS SERVER, enable OPcache in PHP.INI
      zend_extension=php_opcache.dll

      And don't forget to restart Apache on Unix or PHP on WinServer IIS!

    • Gantry 5.2.14 will work with opcache.revalidate_freq>0 and opcache.validate_timestamps=0 settings, though underlying CMS will probably cause still issues.
    • Gantry 5, enjoy!
