Like Spring, but Faster: The new Java Jedi
#1about 4 minutes
The challenge of JVM warmup and resource usage
The JVM's dynamic runtime and Just-In-Time compiler cause slow startup and high resource consumption, which is problematic for containerized microservices.

How Quarkus optimizes startup by shifting work to build time
Quarkus moves framework initialization tasks like configuration and bean injection from runtime to build time, resulting in a pre-warmed and optimized application.

Benchmarking a standard Spring Boot application with AOT
A live benchmark measures the time to first request and RSS memory of a standard Spring Boot application, both with and without ahead-of-time (AOT) compilation.

Migrating to Quarkus and benchmarking JVM performance
By simply swapping dependencies to Quarkus extensions, the same application code demonstrates significantly faster startup and lower memory usage on the JVM.
#5about 7 minutes
Comparing native image performance between Quarkus and Spring
A side-by-side comparison of GraalVM native images reveals that the Quarkus version has a faster build time, smaller binary size, and superior runtime performance.
#6about 3 minutes
The business impact of improved Java performance
Improved performance with Quarkus translates directly to operational cost savings, better resource density in Kubernetes, and a lower carbon footprint for applications.
