Description

Compared to TYPO3 4.5 EId calls in TYPO3 6.2 are very slow.

I made some tests with a simple extension which only includes and executes a mostly empty php file via the Eid mechanism.
tests where made with apache bench on a Windows machine.

ab comandline was: ab.exe -n 1000 -c 8 "url"

APC off        
requests/s
TYPO3 6.2    20    
TYPO3 4.5.30    79    

APC On (shm size = 64m)    
requests/s
TYPO3 6.2    23    
TYPO3 4.5.30    147

you see that 6.2 is roundabout 4 times slower with APC disbled and more than 6 times slower with APC enabled.
If I analyze this calls with a profiler I see that most of the time is wasted in the classloader cache.

Possible solutions:

optimize the classloader performance.
move the Eid Hook to an earlier place in the bootstrapping sequence.
