;These options are for Drupal but should apply to similar applications.
;Setup mostly shows overridden defaults. Please review the documentation!
;http://php.net/manual/en/apc.configuration.php
extension=apc.so
apc.enabled=1
;Min memory of 64M for a very basic Drupal install.
;To check the max shared memory run:
;$ sysctl -a|grep shmmax| awk -F'=' '{print $2/1024/1024 " Mb"}'
;Update sysctl, e.g. 64M:
;$ sysctl -w kernel.shmmax=67108864;sysctl -p /etc/sysctl.conf
;Review and adjust shared memory periodically and whenever code changes are made.
apc.shm_size=160M
apc.shm_segments=1
;On production set to 0 for the best performance so APC doesn't check the file
;before caching it.
;While in active dev setting to 1 may be a better choice.
apc.stat=0
;Experimental and can cause issues!
;Optimize include_once and require_once calls.
;apc.include_once_override=1
;Use APC for CLI mode. Useful for debugging but normally disabled.
;apc.enable_cli=1
;Default 1 but if you want to use apc.filters set to 0.
apc.cache_by_default=1
;Filter files, only used if apc.cache_by_default is disabled. Uses posix
;expression for files to include/ignore based on + and - signs, minus is the
;default. Uses comma separated file names and not absolute paths.
;e.g. Cache all files in "drupal-docroot" and ignore "apc.php" files.
;apc.filters = "+drupal-docroot,apc.php"
;Number of source files to be cached, review apc.php stats to adjust over time.
;default is 1000
apc.num_files_hint=8000
;default of 4096.
apc.user_entries_hint=8000
;Idle cache entry lifetime in seconds, 7200 = 2hrs
;Setting ttl to live to 0 means forever and an apache restart would be needed
;after each code update to clear the caches.
apc.ttl=14400
apc.user_ttl=600
apc.gc_ttl=600
;Defaults to 1M, if you profile you should note any heavy files.
apc.max_file_size=2M
;Enable upload progress, useful in Drupal.
apc.rfc1867=1
;Load only the required functions and classes on-demand.
;Test the usage with your app extensively.
apc.lazy_functions=1
;Determin if your mmap'ed memory region is going to be file-backed or shared
;memory backed. Option 1 is the default but Option 2 is the most common.
;See http://www.php.net/manual/en/apc.configuration.php#ini.apc.mmap-file-mask
; Option 1 (default if not set)
;To mmap directly from /dev/zero, use:
;apc.mmap_file_mask=/dev/zero
; Option 2 (most common)
;Specify the location for file-backed memory storage file.
apc.mmap_file_mask=/tmp/apc.XXXXXX
;Option 3
;For POSIX-compliant shared-memory-backed mmap, use:
;apc.mmap_file_mask=/apc.shm.XXXXXX
