Single-threaded Benchmark.ips, 2s warmup + 5s measure, BenchAPI.call(env) against /api/v1/hello returning a small JSON object. Reproduce with ruby benchmark/version_throughput/run.rb.

Version	No-YJIT (i/s)	μs/req	YJIT (i/s)	μs/req	YJIT speedup
3.0.1	32,565	30.71	54,940	18.20	+68.7%
3.1.1	46,641	21.44	85,694	11.67	+83.7%

Notes

• All versions exercised through the same BenchAPI definition (kept stable in app.rb).
• Results are noisy at this scale (±5-8%); rerun if a number looks off.
• YJIT speedup is (yjit_ips - no_yjit_ips) / no_yjit_ips.
• YJIT pass uses ruby --yjit; both passes share the same Ruby binary.
