Can NodeJS cold-start?

A NodeJS based HTTP service as a comparison

In this installment of the series we are using examples created using NodeJS 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 44 - NodeJS	47 ms	4 ms	51 ms
Example 45 - NodeJS (Docker)	344 ms	3 ms	347 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).
