Core validation logic for pydantic written in rust
Pydantic is quite popular library. Its author is doing exactly this - rewriting its core  in Rust. It's still WIP, but readme mentions that "Pydantic-core is currently around 17x faster than Pydantic Standard."
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
Cannoli Programming Language
This is a great read, and it's fantastic to see all the work being done to evaluate and improve the language!
Shameless plug alert: the dynamic-nature of the language is actually something that I had studied a few years back . Particularly the variable and object attribute look ups! My work was just a master's thesis, so we didn't go too deep into more tricky dynamic aspects of the language (e.g. eval, which we restricted entirely). But we did see performance improvements by restricting the language in certain ways that aid in static analysis, which allowed for more performant runtime code. But for those interested, the abstract of my thesis  gives more insight into what we were evaluating.
Our results showed that restricting dynamic code (code that is constructed at run time from other source code) and dynamic objects (mutation of the structure of classes and objects at run time) significantly improved the performance of our benchmarks.
Yaegi is Another Elegant Go Interpreter
> compiled languages
Might be tripping you up. Very few languages require that implementations be compiled or interpreted. For most languages, having a compiler or interpreter is an implementation decision.
I can implement Python as an interpreter (CPython) or as a compiler (mypyc). I can implement Scheme as an interpreter (Chicken Scheme's csi) or as a compiler (Chicken Scheme's csc). The list goes on: Standard ML's Poly/ML implementation ships a compiler and an interpreter; OCaml ships a compiler and an interpreter.
There are interpreted versions of Go like https://github.com/traefik/yaegi. And there are native-, AOT-compiled versions of Java like GraalVM's native-image.
For most languages there need be no relationship at all between compiler vs interpreter, static vs dynamic, strict or no typing.
Ultra fast asyncio event loop.
If you are building server-side applications using Python 3 and async API and if you didn't use https://github.com/MagicStack/uvloop, you are missing out on performance big time.
Also, if you happen to build microservices, don't forget to try PyPy, that's another easy performance booster (if it's compatible to your app).

A Cython port of Martini for fast RTIN terrain mesh generation
They can! Numpy exposes a C API to other Python programs . It's not hard to write a Cython library that uses the Numpy C API directly and does not cross into Python .

a lightweight, robust, scheme-like lisp implementation
Well let's flip this around: do you think you could write a performant minimal Python in a weekend? Scheme is a very simple and elegant idea. Its power derives from the fact that smart people went to considerable pains to distill computation to limited set of things. "Complete" (i.e. rXrs) schemes build quite a lot of themselves... in scheme, from a pretty tiny core. I suspect Jeff Bezanson spent more than a weekend writing femtolisp, but that isn't really important. He's one guy who wrote a pretty darned performant lisp that does useful computation as a passion project. Check out his readme; it's fascinating: https://github.com/JeffBezanson/femtolisp
You simply can't say these things about Python (and I generally like Python!). It's truer for PyPy, but PyPy is pretty big and complex itself. Take a look at the source for the scheme or scheme-derived language of your choice sometime. I can't claim to be an expert in any of what's going on in there, but I think you'll be surprised how far down those parens go.
Given how many performant implementations of Scheme there are, I just don't think you can claim it's because of complex implementations by well-resourced groups. To me, I think the logical conclusion is that Scheme (and other lisps for the most part) are intrinsically pretty optimizable compared to Python. If we look at Common Lisp, there are also multiple performant implementations, some approximately competitive with Java which has had enormous resources poured into making it performant.
