Best Zend OpCache Settings / Tuning / Configurations
; Determines if Zend OPCache is enabled
; Determines if Zend OPCache is enabled for the CLI version of PHP
; The OPcache shared memory storage size.
; The amount of memory for interned strings in Mbytes.
; The maximum number of keys (scripts) in the OPcache hash table.
; Only numbers between 200 and 1000000 are allowed.
;If you have multiple PHP sites on the server then consider the value 130986
; for magento 2, keep 65406
; The maximum percentage of "wasted" memory until a restart is scheduled.
; When this directive is enabled, the OPcache appends the current working
; directory to the script key, thus eliminating possible collisions between
; files with the same name (basename). Disabling the directive improves
; performance, but may break existing applications.
; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect.
; For Development / testing, keep 1
; For performance / production, keep 0
;opcache.revalidate_freq How often in seconds should the code
;cache expire and check if your code has changed. 0 means it
;checks your PHP code every single request IF YOU HAVE
;opcache.validate_timestamps ENABLED. opcache.validate_timestamps
;should not be enabled by default, as long as it's disabled then any value for opcache.
;revalidate_freq will basically be ignored. You should really only ever enable
;this during development, you don't really want to enable this setting for a production application.
; Enables or disables file search in include_path optimization
; If disabled, all PHPDoc comments are dropped from the code to reduce the
; size of the optimized code.
; If enabled, a fast shutdown sequence is used for the accelerated code
; Depending on the used Memory Manager this may cause some incompatibilities.
; Allow file existence override (file_exists, etc.) performance feature.
; A bitmask, where each bit enables or disables the appropriate OPcache
; passes
; The location of the OPcache blacklist file (wildcards allowed).
; Each OPcache blacklist file is a text file that holds the names of files
; that should not be accelerated. The file format is to add each filename
; to a new line. The filename may be a full path or just a file prefix
; (i.e., /var/www/x blacklists all the files and directories in /var/www
; that start with 'x'). Line starting with a ; are ignored (comments).
; Allows exclusion of large files from being cached. By default all files
; are cached.
; Check the cache checksum each N requests.
; The default value of "0" means that the checks are disabled.
; How long to wait (in seconds) for a scheduled restart to begin if the cache
; is not being accessed.
; OPcache error_log file name. Empty string assumes "stderr".
; All OPcache errors go to the Web server log.
; By default, only fatal errors (level 0) or errors (level 1) are logged.
; You can also enable warnings (level 2), info messages (level 3) or
; debug messages (level 4).
; Preferred Shared Memory back-end. Leave empty and let the system decide.
; Protect the shared memory from unexpected writing during script execution.
; Useful for internal debugging only.
; Allows calling OPcache API functions only from PHP scripts which path is
; started from specified string. The default "" means no restriction
; Mapping base of shared memory segments (for Windows only). All the PHP
; processes have to map shared memory into the same address space. This
; directive allows to manually fix the "Unable to reattach to base address"
; errors.
; Enables and sets the second level cache directory.
; It should improve performance when SHM memory is full, at server restart or
; SHM reset. The default "" disables file based caching.
; Enables or disables opcode caching in shared memory.
; Enables or disables checksum validation when script loaded from file cache.
; Implies opcache.file_cache_only=1 for a certain process that failed to
; reattach to the shared memory (for Windows only). Explicitly enabled file
; cache is required.
; Enables or disables copying of PHP code (text segment) into HUGE PAGES.
; This should improve performance, but requires appropriate OS configuration.
; Validate cached file permissions.
; opcache.validate_permission=0
; Prevent name collisions in chroot'ed environment.
; opcache.validate_root=0
