[TYPO3-dev] Cross-Page caching

[Philipp]

Hey guys

i want to increase the performance of a few pages and the main issue is the uncached page call. I could live with one slow response after cache clearing, but every single page is that slow because typoscript is rendered on each page and all content elements are rendered on each page.

My question:
can i configure some Typoscript chunks as static, so they wont change on other pages?

Kind of

lib.sidebarWidget = COA
lib.sidebarWidget < tt_content.list.20.plugin_signature
lib.sidebarWidget.XXXXX

and at XXXXX i would neeed some settings to share this piece of chunk across all pages.
do i have to create an own plugin and cache the results manually via the CacheManager or does typoscript provide such a function?
