YJIT Benchmarks

Details for Benchmarks at 2025-02-24 03:45:31 UTC

YJIT metrics from the yjit-bench suite using Ruby dfc2520423.

Using the geomean of the headline benchmarks for x86 YJIT 3.5.0dev is
  • 89.7% faster than CRuby 3.5.0dev
  • 7.1% faster than YJIT 3.3.6
On railsbench it is
  • 99.5% faster than CRuby 3.5.0dev
  • 6.0% faster than YJIT 3.3.6
x86_64 runtime: 4 hours, 19 minutes
aarch64 runtime: 3 hours, 40 minutes

Performance on Headline Benchmarks

Speed of each Ruby implementation relative to the baseline CRuby measurement. Higher is better.

Memory Usage on Headline Benchmarks

Memory usage of each Ruby implementation relative to the baseline CRuby measurement. Lower is better.

Performance on Other Benchmarks

Speed of each Ruby implementation relative to the baseline CRuby measurement. Higher is better.

Memory Usage on Other Benchmarks

Memory usage of each Ruby implementation relative to the baseline CRuby measurement. Lower is better.

Performance on MicroBenchmarks

Speed of each Ruby implementation relative to the baseline CRuby measurement. Higher is better.

Memory Usage on MicroBenchmarks

Memory usage of each Ruby implementation relative to the baseline CRuby measurement. Lower 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.
