; This can be set to 0 to disable APCu. This is

; Mostly for testing and debugging.  Setting this enables APCu
; for the CLI version of PHP.  Normally you wouldn't want to
; create, populate and tear down the APCu cache on every CLI

apc.shm_size = 32M

; The number of shared memory segments to allocate

; shared memory but you have already set
; apc.shm_size as high as your system allows, you
; can try raising this value.  Setting this to a

; The number of seconds a cache entry is allowed to
; idle in a slot in case this cache entry slot is

; cached.  
; (Default: 0)

apc.ttl = 7200

; The number of seconds that a cache entry may
; remain on the garbage-collection list. This value

; 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.

; 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 data at the same time.
; By default, APCu attempts to prevent "slamming" of a key.
; A key is considered "slammed" if it was the last key set,
; and a context other than the current one set it ( ie. it
; was set by another process or thread )
; Note:
;     APCu does not store enough information to
;     catch every occurence, sufficient none the less.

; RFC1867 File Upload Progress hook handler is only available
; if you compiled APCu against PHP 5.2.0 or later.  When enabled
; any file uploads which includes a field called 
; APCu_UPLOAD_PROGRESS before the file field in an upload form
; will cause APCu to automatically create an upload_<key>
; user cache entry where <key> is the value of the 
; APCu_UPLOAD_PROGRESS form entry.
;
; Note that the file upload tracking is not threadsafe at this
; point, so new uploads that happen while a previous one is 
; still going will disable the tracking for the previous.

; optionally suffixed with 'k', 'm', or 'g' for kilobytes, 
; megabytes, or gigabytes respectively (case insensitive).  
; A setting of 0 updates as often as possible, which may cause
