; 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

; 16229, 32531, 65407, 130987, 262237, 524521, 1048793 }. Only numbers between

; 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.
; (default "1")
opcache.use_cwd = 1

; When disabled, you must reset the OPcache manually or restart the webserver
; for changes to the filesystem to take effect. The frequency of the check is
; controlled by the directive "opcache.revalidate_freq".
; (default "1")
opcache.validate_timestamps = 1

; How often (in seconds) to check file timestamps for changes to the shared
; memory storage allocation. ("1" means validate once per second, but only once
; per request. "0" means always validate)
; (default "2")

; Prevents caching files that are less than this number of seconds old.
; It protects from caching of incompletely updated files. In case all file
; updates on your site are atomic, you may increase performance setting it
; to "0".
; (default "2")

; Enables or disables file search in include_path optimization.
; If the file search is disabled and a cached file is found that uses the same
; include_path, the file is not searched again. Thus, if a file with the same
; name appears somewhere else in include_path, it won't be found. Enable this
; directive if this optimization has an effect on your applications. The
; default for this directive is disabled, which means that optimization is
; active.
; (default "0")

; If disabled, all PHPDoc comments are dropped from the code to reduce the size
; of the optimized code. Disabling "Doc Comments" may break some existing
; applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)
; (default "1")

; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments" may
; be always stored (save_comments=1), but not loaded by applications that don't

; Enable this hack as a workaround for "can't redeclare class" errors.
; The OPcache stores the places where DECLARE_CLASS opcodes use inheritance
; (These are the only opcodes that can be executed by PHP, but which may not be
; executed because the parent class is missing due to optimization). When the
; file is loaded, OPcache tries to bind the inherited classes by using the
; current environment. The problem with this scenario is that, while the
; DECLARE_CLASS opcode may not be needed for the current script, if the script
; requires that the opcode at least be defined, it may not run. The default for
; this directive is disabled, which means that optimization is active. In
; php-5.3 and above this hack is not needed anymore and this setting has no
; effect.
; (default "1")
opcache.inherited_hack = 1

; 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).
; Files are usually triggered by one of the following three reasons:
; 1) Directories that contain auto generated code, like Smarty or ZFW cache.
; 2) Code that does not work well when accelerated, due to some delayed compile
; time evaluation.
; 3) Code that triggers an OPcache bug.
; (default "")

; Allows exclusion of large files from being cached. By default all files are
; cached.
; (default "0")

; Check the cache checksum each N requests.
; The default value of "0" means that the checks are disabled. Because
; calculating the checksum impairs performance, this directive should be
; enabled only as part of a debugging process.
; (default "0")
opcache.consistency_checks = 0

; How long to wait (in seconds) for a scheduled restart to begin if the cache
; is not being accessed. The OPcache uses this directive to identify a
; situation where there may be a problem with a process. After this time period
; has passed, the OPcache assumes that something has happened and starts
; killing the processes that still hold the locks that are preventing a
; restart. If the log level is 3 or above, a "killed locker" error is recorded
; in the Apache logs when this happens.
; (default "180")
