[Typo3-dev] High parsetime for *_INT objects

[Simon Ihmig]

Hi there,

I realized some strange behaviour regarding the parse parse times I am
unable to explain:
I have a site with 100% fully cached pages (i.e. no USER_INT or COA_INT
objects). The total parsetime as shown in the Admin Panel is around 17ms.

But when I change one COA object into a COA_INT (it does nothing more than
printing the current date/time), the parsetime changes dramatically:
I have a new entry "/Parse template" in my Admin Panel TypoScript output
with around 50-60ms and total parse time is 80-90ms.
The noncached objects execute in virtually no time (0ms).

What's the reason? It should not be that just because of the fact that I
have a non-cached object somewhere in my TS tree, the parse time increases
by 400% (an thus server load!). While 90ms parse time doesn't sound very
huge, IMHO it can have a huge impact on high-volume sites (compared to
17ms).

Any ideas?

btw, I have a couple of other sites with rather large parse times (>200ms)
as well, I guess there is a similiar issue.
