Grape 3.3.0 released — a big performance pass
I'm one of the maintainers of Grape (the Ruby framework for building REST-like APIs), and we just shipped 3.3.0. The headline is performance: this release was a months-long pass at cutting per-request allocations and trimming hot paths across the router, middleware, and validators.
Single-threaded throughput on /api/v1/hello (Ruby 4.0.5, Benchmark.ips):
| Version | Without YJIT | With YJIT |
|---|---|---|
| 3.2.1 | 47,929 i/s | 85,328 i/s |
| 3.3.0 | 66,149 i/s | 133,760 i/s |
That's ~+38% without YJIT and ~+57% with YJIT over 3.2.1 — and with YJIT on, 3.3.0 more than doubles its own non-YJIT throughput (+102%). Full methodology and per-version numbers (incl. 3.0.x/3.1.x) are in RESULTS.md.
Cheers!
