XDebug Profiling

XDebug Config

xdebug.profiler_enable = 1
xdebug.profiler_output_dir = "/path/to/folder/for/cachegrind/files"
xdebug.profiler_output_name = "callgrind.out.%t.%p"

Install QCacheGrind (for OSX Mavericks)

Note: This requires Homebrew be installed. See http://brew.sh/ for instructions.

1. Install QT (this will take a while)

    brew install qt --HEAD
   

2. Install QCacheGrind

    brew install qcachegrind
   

3. Create a Symlink in your Applications folder.

    brew linkapps
   

4. Install Graphviz (for producing call graphs)

    brew install graphviz
    sudo ln -s /usr/local/bin/dot /usr/bin/dot
   

You should be all setup. Now, visit the application in the browser, and it should create files in the path you specified in the XDebug config. Open the QCacheGrind.app application and open one of the files.

Webgrind is also a solid option.
