streamly-examples VS streamly

Regarding the "beat GCC" example (I guess you are talking about the word count example) - we do not claim to beat gcc, I have worked with C/gcc for decades. But it did beat gcc by a thin margin sometimes, but I won't call it beating, rather matching gcc. It does match gcc even now - raise an issue in streamly repo if you cannot reproduce it.

https://github.com/composewell/streamly/issues/1307 seems related, but it was a long time ago. We weren't heavy users anyway, so our streaming philosophy is now "conduit if it's simple and plugging into a conduit-using library, streaming if you're doing complicated things".

Interesting! Which of the streamly modules is implementing that part? Is it one of the workLoop implementations in Streamly.Internal.Data.Stream.Async?

I want to like streamly, but the API is so huge, yet I feel like I'm doing things on a too low level of abstraction. (And as long as it needs a ghc plugin I doubt it'll become the de facto standard.) Though maybe I just haven't used it enough. It does have great docs at https://streamly.composewell.com/ and they seem to be taking both performance, dependency weight and API design quite seriously.

You missed streamly in your list of alternatives: https://github.com/composewell/streamly/blob/master/docs/streamly-vs-async.md
