What if Ruby 4.0 features could be implemented in pure Ruby? With TruffleRuby, that’s possible: 73% of the core library is written in Ruby itself. We currently have 10 issues tagged [easy, pure Ruby] waiting for contributors: github.com/truffleruby/...

I ran your benchmarks from bugs.ruby-lang.org/issues/21824 on TruffleRuby with a slight tweak to use benchmark-ips for warmup and the result is 2.42x faster than CRuby 3.4.8 on the first benchmark and 4.66x faster on the second/minimal benchmark! See gist.github.com/eregon/e3692... for details.

Running native extensions in parallel is a huge performance boost. Running a large internal Rails application, we saw performance roughly double. Very workload dependent, of course, but all of the major DB adapters are implemented as native extensions. We also added support for the blake3-rb gem.

TruffleRuby can now run C/native extensions in parallel, just like Ruby code runs in parallel in Threads on TruffleRuby! Native extensions need to opt in with rb_ext_ractor_safe(true) or rb_ext_thread_safe(true). Many gems already do that. See github.com/oracle/truff... for more details.
