The performance of backendmodules seems to be very bad. We have to analyze that and look, how to improve.
This is just an umbrella issue, if you want to discuss specific issues, please open sub-issues. thanks.

Please find attached a screenshot of a diff between two profiling runs of a 6.2 installations.
One (run2) has the sys_note extension loaded and the other has not.
You see a 300% increase in number of function calls. Also a 500% increase in load time.
I'll try do dig some more.

Hi Felix. A sub issue? This is one issue. The problem is indeed the TypoScript parsing. The total callgraph looks horrible. There is a lot of TYPO3\CMS\Core\TypoScript\Parser\TypoScriptParser::parseSub@n going on. All is initiated by TYPO3\CMS\Core\TypoScript\TemplateService::generateConfig. I don't see anything like this for frontend pages with extbase extensions. I don't understand why the normal and fast runthroughTemplates is not enough to get the TS.
