In this installment of the series we are using examples running on WildFly to cold start the 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 14 - WildFly 2,002 ms 84 ms 2,086 ms
Example 15 - WildFly (Docker) 7,788 ms 141 ms 7,929 ms
