Zero Waste, Radical Magic, and Italian Graft – Quarkus Efficiency Secrets

on YouTube ↗51m

" summary

Quarkus shifts heavy work from runtime to build time, using a Jandex offline index and an extensible build steps/build items model so libraries participate in the speedup; JVM mode keeps high throughput while native (GraalVM) starts in tens of milliseconds and keeps a tiny memory footprint. A cache‑pollution bug fix raises measured throughput from about 1.8M to 5.8M req/s; some hot‑path fixes replace idiomatic code (instanceof) with uglier but faster alternatives. Dev mode live coding hides build‑time costs and a Vert.x reactive core remains optional.
