Spring WebFlux Performance

The Spring WebFlux is reactive and non-blocking. The advantage of Spring WebFlux is the ability to scale with a small, fixed number of threads and less memory. The Spring WebFlux applications are more resilient under load. The reactive stack shows it strength when we have some latency, for example, slow and unpredictable network.
