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.

1BRC Merykitty's Magic SWAR: 8 Lines of Code Explained in 3k Words
What an amazing step by step explanation!
More than 2 years ago I found that byte array view var handles are quite suitable to cook efficient SWAR routines with Java/Scala.
See a lot of other examples of SWAR usage, like parsing Base16/64 string, java.time.* and number values directly from byte arrays:

The Newest Java Json Benchmark Results just dropped
Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

Please try my JSON library
I was on your place more then 5 years ago, when cut the 1st release of jsoniter-scala.

smithy-translate : a CLI tool to turn openapi specs and json-schema specs into smithy specs, written in Scala
We have our own open-source code-generator that produces Scala code from Smithy. The code module is entirely dependency-free, and the generated code is not biased towards any library, be that http or json. We do however have out-of-the-box integration with jsoniter and http4s.

Why does Scala seem to be slow at benchmark results?
You can use jsoniter-scala. It is easy to use like upickle.

BEWARE: uJson is vulnerable under DoS attacks

Is Scala a good choice for a data intensive web backend?
Please see sources (and GitHub history of development) of jsoniter-scala as an example in the domain of JSON parsing and serialization.

Learning macros in scala 2.13
I suggest looking into jsoniter-scala Macro API it has unique support of both Scala 2 and Scala 3 in a source compatible manner.

Using SWAR techniques to speed up parsing and serialization from/to JSON
Since v2.13.6 release jsoniter-scala dropped support of Java 8: https://github.com/plokhotnyuk/jsoniter-scala/releases/tag/v2.13.6
SWAR (SIMD in register) techniques were used in the last release of jsoniter-scala to speed up parsing and serialization on JVM platforms.

Abstraction layers over the various JSON libraries?
Seems like the accepted solution is to have a separate subproject for each of the ~5 major json libraries. For example see elastic4s (elastic4s-jackson, elastic4s-circe, ...) or akka-http-json.
What are some alternatives?
circe - Yet another JSON library for Scala
json4s - JSON library
DSL-JSON - High performance JVM JSON library
Slick - Slick (Scala Language Integrated Connection Kit) is a modern database query and access library for Scala
jackson-module-scala - Add-on module for Jackson (https://github.com/FasterXML/jackson) to support Scala-specific datatypes
Play JSON - The Play JSON library
spray-json - A lightweight, clean and simple JSON implementation in Scala
ReactiveCouchbase - Play 2 plugin for ReactiveCouchbase
Shade - Memcached client for Scala
None Is Not Null - JSON typeclasses that know the difference between null and absent fields
sbt-json - sbt plugin that generates Scala case classes for easy, statically typed and implicit access of JSON data e.g. from API responses
doobie - Functional JDBC layer for Scala.
