Update after longer run (~10M cycles): max jitter reached 55 µs 👌🏻
Plugging in AC power caused a localized spike on a single RT thread (51 µs), while others stayed stable.
Classic ACPI / power-state event: bounded, localized, fully recoverable.
Determinism preserved under real hardware events 👊🏻

Again my custom Linux RT OS from scratch with Buildroot on Raspberry Pi 4.
Wi-Fi and OpenVPN are up, real apps running (wpa_supplicant, mosquitto, dropbear…), and yet cyclictest shows max latency under 50µs, even under stress-ng load.
Real-time performance, real-world conditions. I'm impressed.

BashCoreZ just proved it's the ultimate Real-Time base! 🚀
Tested the ultra-minimal #BashCoreZ (Debian 13 + Kernel 6.12 #PREEMPT_RT) using #cyclictest, remotely piloted from a #BashLabOS host.
Result: Max Jitter stayed under 240µs! That’s incredible determinism for embedded, robotics, and industrial control.
The "zero bloat" foundation truly eliminates noise.
