Optimizing Incremental Source Generator Performance: Is It Beneficial to Separate Types with Distinct HintNames?

[devbased]

I am developing an incremental source generator that generates numerous types, ranging from dozens to even hundreds. The entire code is constructed using a single StringBuilder, and subsequently, the resulting string is added via SourceProductionContext.AddSource along with a specific hintName. I am wondering whether it would be beneficial to separate these types and write each with its own distinct hintName?
I'm not sure how to correctly measure the performance of the generator. I suppose if the IDE doesn't slow down, then it's considered fast 😅
