Attaching the same data but in JFR format, although that seems harder to me IMO:
[flamegraph_quarkus_db_256_jfr.zip](https://github.com/user-attachments/files/20999270/flamegraph_quarkus_db_256_jfr.zip)

To see the overhead on the flamegraphs you can open it in a browser, hit "CTRL+F" and type a relevant string, for example  "ResourceLock" . This will highlight the areas to zoom in in purple, and the bottom right corner on the screen will give you the aggregate stats among all callers.
