The Meltdown Curve: Why 95% Busy Means 20x Slower

Your dashboard says 92% CPU.
Your team says "we still have headroom."
Your users say the app is unusable.

Who is lying?

Nobody. And that is the trap.

Utilization is not remaining capacity. The math of queues guarantees that wait times explode long before you hit 100% - at 95% busy, latency is already 20x worse than baseline.
Most teams learn this at 3 AM during an outage.

I am scheduling a deep-dive session in my meetup group, Software Architecture by Diagrams.
If you have ever debugged a slow system that was "not even full" - this session is for you.
