There is still a common belief about Java being slow (especially during the startup)
and memory-consuming, making it not being the first option for ephemeral service
instances, like containers. This blog post pretends to put some light on
those assertions, quantifying the impact of a last-generation JVM in a simple,
single-threaded, application. We compare the impact of the JVM measuring the
execution time and memory spent of a Java QuickSort implementation,
comparing it with the execution of a native image generated with the modern
GraalVM Ahead-Of-Time (AOT) compiler and the same
QuickSort implementation in Go.

the code syntax according to the Alec Thomas' Chroma engine and styles.

to the same struct, returning a struct value may be faster than returning a
pointer if we consider escape analysis particularities.
