I would like to insert fragments from external services. Thymeleaf documentation allows us to do so (https://www.thymeleaf.org/doc/articles/layouts.html#including-with-markup-selectors). I'm wondering about the performance on requesting many fragments from different servers, how the consumption of those external resources is done basically. Is it done in parallel/reactive way or are they serialised somehow? Of course the final rendering of the page needs to have all the fragments, but the connection to each server could be done as soon as possible.
Any insight on this?
Thank you.
