Can Java cold-start?

A GraalVM based HTTP service

In this installment of the series we are using examples created using just GraalVM to cold start a HTTP server.

If you want to run the experiment yourself you can download the example.tar.gz file.

Example	Process start	Process ready	Process total
Example 41 - GraalVM	57 ms	39 ms	96 ms

These numbers were collected on a Mac Mini M1 with 16GB using Java 17

Note the generated x86 binary causes Rosetta2 to be used as there currently is no native M1 support for GraalVM

Legend

Process start - the amount of time it takes before the JVM is executing your code.
Process ready time - the amount of time it takes for the HTTP server to be ready for processing.
Process total - the total time (process start + process ready).
