Tag Archives: apc

I’ve been enjoying using the keg homebrew-php by josegonzalez in order to run the latest versions of PHP, like PHP 5.4 on Mac running OS X 10.8 Snow Leopard. I also like to use Ubuntu on some cloud web servers and have been noticing a huge improvement in performance when the php module apc is installed / enabled. Recently I learned that I can get this same performance boost on in my development environment on my mac by using apc here too. Just install it with homebrew: brew install php54-apc The module will be installed and enabled, and on my system it created a new config file called ext-apc.ini in the directory /usr/local/etc/php/5.4/conf.d and it has some great defaults: [apc] extension=”/usr/local/Cellar/php54-apc/3.1.10/apc.so” apc.enabled=1 apc.shm_segments=1 apc.shm_size=64M apc.ttl=7200 apc.user_ttl=7200 apc.num_files_hint=1024 apc.mmap_file_mask=/tmp/apc.XXXXXX apc.enable_cli=0 One key here is that apc.shm_size needs to be set, and that it also needs to have the suffix M or I guess you could use K if you wanted a really small shm_size but honestly 64M works pretty great.
