The number 3 is very significant in the Ruby 3 release. Be it release version number, making performance 3x faster, or the trio of core contributors(Matz, TenderLove, Koichi).
Similarly, there were 3 major goals of Ruby 3: being faster, having better concurrency, and ensuring correctness.
Ruby 3’s main selling point is that it’s 3 times faster than Ruby 2. Matz and the team have been trying to bring in a lot of features in the latest version of Ruby, but their foremost priority has been to ensure that performance is improved drastically, and that backward compatibility is maintained.
There are a whole bunch of new additions like type checking, ractor, and scheduler, along with improvements to the currently existing paradigms, like performance, fibers, memory, concurrency, and static analysis. We’ll take a deeper look at each one of them one-by-one.
One of the most promising updates for Ruby CPU performance is the new Ruby JIT.
Another new feature that might significantly improve the programming language’s performance is the Medium Internal Representation JIT compiler, which is lightweight and convenient to work with.
We hope that this Ruby updates will actually be included in Ruby 3.0 since it might solve Ruby’s issues and result in significant performance improvement beyond the current JIT.
The point of a new big number is that it breaks stuff from previous releases.
One final note: In order to manage projects developed on different versions of Ruby, you’ll want a version manager to allow you to easily switch back and forth. I’ve used rbenv; I’m also aware of chruby and RVM that are frequently recommended and accomplish the same thing.
