3) Why? As a performance troubleshooter consultant+trainer, I regularly have to reproduce complex problems that show up only under high concurrency & load - stuff that you can't just reproduce in a VM in a laptop.
4) Fun - seeing if the "next gen" hardware's promised performance is actually possible!
FYI I have some videos from my past complex problem troubleshooting adventures, mostly Oracle stuff so far and some Linux performance troubleshooting:
1) Learning & researching capabilities of modern HW
2) Running RDBMS stress tests (until breaking point), Oracle, Postgres+TimescaleDB, MySQL, probably ScyllaDB soon too
