Playback Startup Latency: What to Measure First

A simple measurement order for reducing user-perceived startup delay in media products.

Teams often start optimization from codecs or CDN tuning. That can help, but only after basic path breakdown is clear.

Start with three segments:

  1. Session setup latency
  2. First-byte-to-first-frame latency
  3. Buffer stabilization latency

The biggest gains usually come from reducing retries and eliminating avoidable round trips in startup orchestration.
