A few days ago we switched our complete infrastructure from hosting provider. Also we made the switch from CentOS to Debian. So we also got a new fresh development environment using Debian and Vagrant (and latest PHP and MySQL ofcourse :)).
We expected the new dev box to be fast, but the oppositie was happening: it was slow as hell. And when I mean slow as hell, it’s terribly slow (10 – 20 seconds, also for the debug toolbar). In the past we had some more problems with performance on VirtualBox and Vagrant. There are some great post out there on this subject (here and here) which we already applied to our setup. In a nutshell:
- change logs and cache dir in AppKernel
- use NFS share
The cause: JMSDiExtraBundle
After some profiling I discovered there were so many calls originating from JMSDiExtraBundle I tried to disable the bundle. And guess what: loading time dropped to some whopping 200ms!
The real problem was the way the bundle was configured:
|
1 2 3 4 5 |
jms_di_extra: locations: all_bundles: false bundles: [SomeBundle, AnotherBundle] directories: ["%kernel.root_dir%/../src/Vendor/Model"] |
This causes the bundle to search trough all your php files in those locations. Apparently in the old situation (php 5.3 and CentOS) this wasn’t as problematic as in the new situation (php-fpm 5.5, Debian).
