My machine: OS X Yosemite Beta 2, Vagrant 1.6.5 using VirtualBox as a provider.

I'm finding that PHP's opcache setting means it takes about 60 seconds for any change to a PHP file to be "picked up" when developing using synced folders. Changes to any other synced file are picked up instantly, and it's not related to caching in the browser.

Disabling the opcache in /etc/php5/fpm/php.ini (opcache.enable = 0) lead to instant reloads, as expected.

If anyone else is experiencing this, perhaps the opcache could be disabled during development?
