LLM Streaming TTFT & Token Chunk Visualizer
Simulate Server-Sent Events (SSE) token chunks in real time. Inspect Time to First Token (TTFT), inter-token arrival variance (jitter), and avoid React re-render thrashing.
Stream Profile Parameters
Time to First Token (TTFT) 180ms
Generation Throughput 280 tok/s
💡 Frontend Performance Pro Tip
Calling setState on every single token from high-speed engines (200+ tok/s) locks the browser main thread. Always buffer incoming SSE chunks inside a useRef and flush via requestAnimationFrame.
