Benchmarking programming languages and web frameworks

Vert.x: Semeru vs Temurin

Vert.x is a toolkit for building reactive applications on the JVM designed to be lightweight, high-performance, and modular. It enables developers to create microservices and distributed systems with ease through an event-driven, non-blocking development model. Vert.x supports multiple programming languages and emphasizes performance and scalability.

This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.

Comparison

Temurin processes 1.16x requests per second compared to Semeru, a 16.06% improvement.

Mode	Requests per second Indicates how many requests per second the framework can handle. (higher is better)	Latency Indicates how long it takes to process a request. (lower is better)	Stability Indicates how stable the framework is under load: median / P99 latency (higher is better)	Memory Indicates how much memory (RAM) the framework uses. (lower is better)
Temurin	23116 (+16.06 %)	1.3 ms (-13.53 %)	66.75 % (+3.45 %)	484.4 MB (+253.58 %)
