This comes across as totally meaningless. Even ignoring the fact that this corresponds to no real world use of ZF there is way too much detail here for it to be useful.

For a comparison to other PHP applications see this post: http://blog.fedecarg.com/2008/08/04/php-applications-where-i...

This graph is produced by KCacheGrind from a backtrace file produced by XDebug (http://xdebug.org/). The combination of these tools is very valuable in identifying performance problems in PHP applications. Not at this level of detail, though :)

Anyone know a similar program for Mac?

KCacheGrind works on the mac. Install it via MacPorts or Fink. I've blogged about this waybackwhen:

And if you don't bother installing KDE3 on your Mac, there's also

http://www.maccallgrind.com/

and

http://ccg.wiki.sourceforge.net/

and

http://code.google.com/p/webgrind/

All three tools parse the profiling Output that's generated by XDebug which runs perfectly well on a mac, or on any machine PHP runs on.

This might also be used as an educational tool for exploring the intricacies of the Zend FW. Especially those parts in which the Zend handles the 'View' and 'Controller' of the MVC :)

Are there charts like this for some of the other PHP frameworks? CodeIgniter, CakePHP and Yii would be good ones to look at.

Does anyone know one of these graphs for ruby on rails? i have a feeling it should be really huge

How about showing us the code for the Hello World script as well?

wow. suddenly i realized that i have so much to understand about Zend Framework.
