Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Haskell adoption is higher than I expected, what can we do to get it to top 10 languages.
Don't get me wrong, we figured it all out, and currently we use Aeson fork as we needed this: https://github.com/haskell/aeson/pull/926, as the default behaviour didn't work with Swift, and I wasn't sure if it's worth spending any time completing it...

How would aeson redesign FromJSON without intermediate Value?
Simdjson-based Hermes is able to decode JSON significantly faster while still using an intermediate representation: https://github.com/haskell/aeson/pull/923

Text Maintainers: text-utf8 migration discussion - Haskell Foundation
Similar scan is already in aeson https://github.com/haskell/aeson/blob/master/src/Data/Aeson/Parser/Internal.hs#L322-L335 where the unsafeDecodeASCII is used I mentioned in my previous comment.

High-performance JSON codec
I'd be curious to see the benchmarks with the cffi flag enabled. aeson by default uses Haskell instead of C and this results in a pretty massive slowdown - the benchmark in that PR shows FFI being 12x faster.
Well, the aeson’s ffi code is written by me: https://github.com/haskell/aeson/commit/2f24e555d86a36fdda6d4cad79976004b382ab3b
