[TYPO3-dev] Slow BE-Performance in 4.5 - doubled system calls?

[Kay Strobach]

I missed the most important step!

-> Use debian ;)

The worst performance i measured was on solaris (sorry oracle) followed
by Windows. Using debian on the same maschine was just 3 times faster.
During the install just install the lamp stack and NO grafical
userinterface ;)
