[Typo3-dev] Higher parsetime in 3.8.0

[Simon Ihmig]

Hello,

I just updated one site to TYPO3 3.8.0, and realized that the average
parsetimes were substantially higher.
Find below the output of the admin panel for 3.7.0 as well as 3.8.0:

The line "/Page generation" seems to be the cause: it went from 1ms to
146ms. Any clue?

BTW, when there is no "/Non-cached objects" (no USER_INT), parsetime is
around 26ms for both TYPO3 versions, which rises the question again (which I
asked already some time ago) why a single, simply USER_INT has to lead to
such dramatic loss of performance!? (almost tenfold!)

I simply can't afford to use non-cached objects for high-volume sites! :-(
