75 MILLION cycles & 24h stress test: PASSED.

​Final verdict on #RaspberryPi 4 + #Buildroot + Linux 6.19-rc1 PREEMPT_RT:

Max jitter: 118us (under heavy stress)
Max jitter: 70us (post-stress/idle)

​Perfect recovery, zero drift, and absolute determinism. This $50 setup is officially outperforming industrial hardware 10x its price. The future of #RTLinux is here 👊🏻

30 MILLION cycles. Max jitter: 118us. Solid as a rock. 🏁

Final report on my #Buildroot + #RaspberryPi 4 setup with Linux 6.19.0-rc1-v8 PREEMPT_RT.

After 8+ hours of torture:
🔥 stress-ng (2x VM workers)
📶 Active SSH over Wi-Fi
📊 Avg Jitter: 14us | Worst Case: 118us

The kernel isn't even stable yet, but this real-world performance is already production-ready. We are ready for the future of #RTLinux. 👊🏻
