The performance difference is really interesting.
Did you try comparing Dictionaries with e.g. similar DotNet objects like the JsonObject type or older NAV types like the arrays (which are able to store complex types like Records, unlike the other two)?
I also found your video on TextBuilder vs Text to be informative, I would’ve thought the compiler itself would optimize text concatenation, especially simple ones (appending to the same string in a loop).
