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.

It can now run native extensions in parallel, just like Ruby code already ran in parallel in Threads on TruffleRuby!
It also features many compatibility improvements and notably support for custom Digest algorithms.

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.

Though with @truffleruby.bsky.social one can in fact just #send it, even publicly, at 276 million iterations/second in all 3 cases! gist.github.com/byroot/780c1... (using the benchmark from bsky.app/profile/byro...)
In hot code paths, do not listen to this man. You should, in fact, _not_ send it
