An airhacks.fm conversation with Holly Cummins (@holly_cummins (twitter.com/holly_cummins)) about:
discussion about Quarkus (quarkus.io) energy efficiency and performance benchmarks,
comparing Quarkus throughput and energy consumption to Spring Boot,
the Quarkus Benchmarks repository (github.com/quarkusio/benchmarks) and Spring-Quarkus performance comparison repository (github.com/quarkusio/spring-quarkus-perf-compa…) on GitHub,
three times throughput and half the energy consumption with Quarkus,
Quarkus build-time optimization and tree shaking (en.wikipedia.org/wiki/Tree_shaking),
monomorphic vs megamorphic dispatching in the JVM,
removing reflection at build time,
the reactive core built on Vert.x (vertx.io) enabling blocking APIs with reactive scalability,
Quarkus dev experience and fast reload,
build duration comparison between Quarkus and Spring Boot,
the Writing Greener Java Applications (hollycummins.com/writing-greener-java-applicat…) white paper,
the Energy Efficiency across Programming Languages study,
Java (java.com/en) ranking among the most energy-efficient languages,
carbon-aware dispatching and Electricity Maps (electricitymaps.com),
zombie deployments and kubernetes.io cluster waste,
serverless (en.wikipedia.org/wiki/Serverless_computing) architecture with Quarkus on AWS Lambda (aws.amazon.com/lambda),
SnapStart for sub-second cold starts,
Provisioned Concurrency (aws.amazon.com/blogs/aws/new-provisioned-concu…) cost savings,
GraalVM (graalvm.org) native binaries vs JVM mode in serverless environments,
CycloneDX (cyclonedx.org) SBOM generation in Quarkus,
build-time vs runtime configuration for ISO 27001 security certification,
Kruize Autotune (github.com/kruize/autotune) for JVM hyperparameter optimization,
JVM tuning folk wisdom and the copy-paste typo anecdote,
Francesco Nigro's performance optimization work across the stack from assembly (en.wikipedia.org/wiki/Assembly_language) to JVM,
Jeff Mesnil leading JBoss (jboss.org) energy efficiency efforts,
cheese fondue recipe,
UK chocolate and Cadbury Roses
