Overall YJIT is 32.2% faster than interpreted CRuby!
On Railsbench specifically, YJIT is 30.4% faster than CRuby!
The basic "faster" measurement is the geomean of all "headlining" x86 benchmarks on this page.

Headlining Benchmarks
These are "headlining" because the "overall" speedup above is based on these benchmarks specifically.
Speed of each Ruby implementation (iterations/second) relative to the CRuby interpreter. Higher is better.
Other Benchmarks
Speed of each Ruby implementation (iterations/second) relative to the CRuby interpreter. Higher is better.
MicroBenchmarks
Speed of each Ruby implementation (iterations/second) relative to the CRuby interpreter. Higher is better.

Different Ruby configurations want different amounts of warmup. With no JIT, CRuby needs hardly any. YJIT and MJIT 3.0 both warm up quite quickly, while MJIT in 3.1 often slows down for a time as it compiles, after an unpredictable delay.
