[TYPO3-core] RFC 17978 -.... 30% performance drop without discussion

[Kay Strobach]

Hi,

i also did some tests, and must second Alexander.

Mhmm, i like the architektural idea behind the patch to make things
easier. But we also MUST take care of speed and memory usage.

I currently have no time to digg deeper into the problem, as i'm working
hardly in the theming stuff.

Regards
Kay
