Ruby 3.3's YJIT: Faster While Using Less Memory

Truffle Ruby is 50-100% faster in most tests.

But uses 5-10x more memory.

Still has way more upside left to gain.

Not to mention the warm-up time - the graph in the referenced article is measured in seconds, with max > 20!

Can attest, just pulled TruffleRuby (both native and JVM), it is over ten seconds to start a hello world script cold. As in, script being run from command line as needed.

These are gains that are only going to make sense for the long-running process crowd.
