PICTURE THIS: HOW TO EXPLAIN IT

IdeaLatency and Throughput

HowWhat happens inside

Why they askShows real use

Simple meaning

Increase batch size or concurrent streams, use multi-model Triton instances, or bin-pack more replicas per GPU if memory allows.

WHY — Latency and Throughput instead of guessing?

Why interviewers care about Latency and Throughput:

Latency and Throughput questions

separate people who only read docs from people who shipped.

Keep it short, concrete,

and tied to MLOps work.

Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

End with when you use it and one common pitfall.

STEPS — What happens step by step?

Before you speak the answer, walk the interviewer through these steps:

1
Increase batch size or
concurrent streams, use multi-model Triton instances, or bin-pack more replicas per GPU if memory allows.
2
If QPS is inherently
low, move to CPU or a smaller accelerator.
3
Utilization without an SLO
check is not a win if you wreck p99.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
Close
When you pick this over the alternative.

Key takeaway

Increase batch size or concurrent streams, use multi-model Triton instances, or bin-pack more replicas per GPU if memory allows. If QPS is inherently low, move to CPU or a smaller accelerator.
