Can Ruby cold-start?

A Ruby based HTTP service

In this installment of the series we are using examples created using Ruby to cold start a HTTP service.

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

Example	Process start	Process ready	Process total
Example 42 - Ruby	80 ms	0 ms	80 ms
Example 43 - Ruby (Docker)	384 ms	0 ms	384 ms

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

Process start - the amount of time it takes before the runtime 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).

If you have any comments, suggestions or concerns, please start a discussion on GitHub.
