Notes:
 * Timings are from one machine (Temurin 25.0.4.1+1, Linux x86_64, container) and are
   indicative. The ratios between rows are the point, not the absolute numbers.
 * "no tracking" and the two instrumented rows overlap. Recording startup steps is not
   measurably slower than not recording them on this application.
 * The AOT cache was trained on this exact jar with -XX:AOTMode=record and assembled with
   -XX:AOTMode=create. It is 118 MB and is invalidated by a classpath change.
