LATENCY & PERFORMANCEAI SRE

Queueing and Backpressure

Queueing occurs when incoming AI work arrives faster than serving capacity can process it.

WHY IT MATTERS

Queue growth rapidly turns a capacity problem into a user-latency incident.

PRODUCTION EXAMPLE

GPU utilization reaches 96%, pending requests rise from 20 to 600 and p95 TTFT jumps from 1.1s to 9s.

SRE DECISION

At what queue depth do you shed load, route elsewhere or degrade gracefully?

REMEMBERA growing queue is an early warning that latency is about to fail.
