[TYPO3-core] Speed improvements in ClassLoader

[Robert Lemke]

Hi folks,

just my 2 cents regarding measurement of speed improvements: from my experience, and especially since the Flow performance code sprint we had recently, I would not use Apache Bench for measuring code improvements - there are just too many layers involved.

We had much more meaningful results with Nodeload (https://github.com/benschmaus/nodeload) for testing "from outside" and XHProf for a view at what's happening inside.

Hope that helps at some point,

Cheers,
Robert
