File apc.ini of Package php5-APC

extension=apc.so
; This can be set to 0 to disable APC. This is
; primarily useful when APC is statically compiled
; into PHP, since there is no other way to disable
; it (when compiled as a DSO, the zend_extension
; line can just be commented-out).
; (Default: 1)
;
apc.enabled=1

; The number of shared memory segments to allocate
; for the compiler cache. If APC is running out of
; shared memory but you have already set
; apc.shm_size as high as your system allows, you
; can try raising this value.
; (Default: 1)
;
apc.shm_segments=1

; The size of each shared memory segment in MB.
; By default, some systems (including most BSD
; variants) have very low limits on the size of a
; shared memory segment.
; (Default: 30)
;
apc.shm_size=128

; The optimization level. Zero disables the
; optimizer, and higher values use more aggressive
; optimizations. Expect very modest speed
; improvements. This is experimental.
; (Default: 0)
;
apc.optimization=0

; A "hint" about the number of distinct source files
; that will be included or requested on your web
; server. Set to zero or omit if you're not sure;
; this setting is mainly useful for sites that have
; many thousands of source files.
; (Default: 1000)
;
apc.num_files_hint=1024

; Just like num_files_hint, a "hint" about the number
; of distinct user cache variables to store.
; Set to zero or omit if you're not sure;
; (Default: 100)
;
apc.user_entries_hint = 100

; The number of seconds a cache entry is allowed to
; idle in a slot in case this cache entry slot is
; needed by another entry.  Leaving this at zero
; means that your cache could potentially fill up
; with stale entries while newer entries won't be
; cached.
; (Default: 0)
;
apc.ttl=7200

; The number of seconds a user cache entry is allowed
; to idle in a slot in case this cache entry slot is
; needed by another entry.  Leaving this at zero
; means that your cache could potentially fill up
; with stale entries while newer entries won't be
; cached.
; (Default: 0)
;
apc.user_ttl=7200

; The number of seconds that a cache entry may
; remain on the garbage-collection list. This value
; provides a failsafe in the event that a server
; process dies while executing a cached source file;
; if that source file is modified, the memory
; allocated for the old version will not be
; reclaimed until this TTL reached. Set to zero to
; disable this feature.
; (Default: 3600)
;
;apc.gc_ttl = 3600

; On by default, but can be set to off and used in
; conjunction with positive apc.filters so that files
; are only cached if matched by a positive filter.
; (Default: On)
;
; apc.cache_by_default = On

; A comma-separated list of POSIX extended regular
; expressions. If any pattern matches the source
; filename, the file will not be cached. Note that
; the filename used for matching is the one passed
; to include/require, not the absolute path.  If the
; first character of the expression is a + then the
; expression will be additive in the sense that any
; files matched by the expression will be cached, and
; if the first character is a - then anything matched
; will not be cached.  The - case is the default, so
; it can be left off.
; (Default: "")
;
; apc.filters = ""

; If compiled with MMAP support by using --enable-mmap
; this is the mktemp-style file_mask to pass to the
; mmap module for determing whether your mmap'ed memory
; region is going to be file-backed or shared memory
; backed.  For straight file-backed mmap, set it to
; something like /tmp/apc.XXXXXX (exactly 6 X's).
; To use POSIX-style shm_open/mmap put a ".shm"
; somewhere in your mask.  eg.  "/apc.shm.XXXXXX"
; You can also set it to "/dev/zero" to use your
; kernel's /dev/zero interface to anonymous mmap'ed
; memory.  Leaving it undefined will force an
; anonymous mmap.
; (Default: "")
apc.mmap_file_mask=/tmp/apc.XXXXXX

;
; On very busy servers whenever you start the server or
; modify files you can create a race of many processes
; all trying to cache the same file at the same time.
; This option sets the percentage of processes that will
; skip trying to cache an uncached file.  Or think of it
; as the probability of a single process to skip caching.
; For example, setting this to 75 would mean that there is
; a 75% chance that the process will not cache an uncached
; file.  So the higher the setting the greater the defense
; against cache slams.  Setting this to 0 disables this
; feature.
; (Default: 0)
;
;apc.slam_defense = 0

;
; When you modify a file on a live web server you really
; should do so in an atomic manner.  That is, write to a
; temporary file and rename (mv) the file into its permanent
; position when it is ready.  Many text editors, cp, tar and
; other such programs don't do this.  This means that there
; is a chance that a file is accessed (and cached) while it
; is still being written to.  This file_update_protection
; setting puts a delay on caching brand new files.  The
; default is 2 seconds which means that if the modification
; timestamp (mtime) on a file shows that it is less than 2
; seconds old when it is accessed, it will not be cached.
; The unfortunate person who accessed this half-written file
; will still see weirdness, but at least it won't persist.
; If you are certain you always atomically update your files
; by using something like rsync which does this correctly, you
; can turn this protection off by setting it to 0.  If you
; have a system that is flooded with io causing some update
; procedure to take longer than 2 seconds, you may want to
; increase this a bit.
; (Default: 2)
;
;apc.file_update_protection = 2

; Mostly for testing and debugging.  Setting this enables APC
; for the CLI version of PHP.  Normally you wouldn't want to
; create, populate and tear down the APC cache on every CLI
; request, but for various test scenarios it is handy to be
; able to enable APC for the CLI version of APC easily.
; (Default: 0)
;
apc.enable_cli=1

; apc.max_file_size       Prevents large files from being cached.
;                         (Default: 1M)
;
;apc.max_file_size = 1M

; Whether to stat the main script file and the fullpath
; includes.  If you turn this off you will need to restart
; your server in order to update scripts.
