246	Install A PHP System Profiler	khaled	khaled	"We need to add a profiling utility to examine our PHP platform source code and see where we can make delivery performance improvements.

There are two primary competitors for this:
APD: [http://pecl.php.net/package/apd]
kCacheGrind (uses XDebug): [http://kcachegrind.sourceforge.net/]

There is some discussion that while KCacheGrid is better looking, APD is more accurate (repeated tests with APD yield the same results, not so with KCacheGrind).

Deploying something like is a must for future profiling and testing of platform code."	application	new	major	Administrative Tasks	main web platform		Evaluating (Tech)
