Since the code is near final, I have measured the gain again. No surprise here.
We have tried it on real web-pages, but unfortunately we experinced about 100%
deviation, so the comparison is useless.

(I got a message now, that the regressions are passed on mac as well! Excellent
news for me)

charlie137, would you repeat your measurements again?
