Problems / LLM serving, easy
Each answer streams for about 4 seconds, and the deployment allows 100 concurrent streams. Traffic is 40 requests a second.
Free to open. Runs in your browser, no sign-up.
Success ≥ 99%, time to first token p99 ≤ 2.5 s.
40 requests a second for 30 seconds: 100% request (reads).
What each component does in this design, and what calls it. The simulator mimics each one from these settings.
| Component | Its job here | Settings |
|---|---|---|
| Load balancerLoad balancer | Traffic enters here.Calls AI app.Layer 4 balancers route by IP and port; layer 7 balancers read HTTP and can route by path or header. | – |
| AI appApp service | Load balancer forwards to it.Calls Model.Little's law: throughput ≈ concurrency ÷ latency. 200 slots at 50 ms serve about 4,000 req/s. | 3 replicas × 500 slots · timeout 30 s |
| ModelLLM endpoint | AI app calls it.Latency has two parts: time to the first token, then a steady stream of tokens per second. | 100 streams |
Try it first. Open one hint at a time if you get stuck.
Little’s law: streams in use = rate × stream time.
40 × 4 s = 160 streams.
Raise the concurrent streams (or provisioned throughput) above 160 with headroom.
