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 25.0 is released! 🚀🎉
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.

TruffleRuby 24.2 is released!🚀🎉
It uses the new Java Panama API in JVM mode to speedup C extensions like sqlite3, trilogy and json by 2 to 3 times!
It also redesigns encoding negotiation for speed, and updates to Ruby 3.3!
