DNS Prefetch Benefit by Latency Calculator

Calculate the page load improvement from DNS prefetch and preconnect hints for third-party domains. Model the latency savings based on DNS resolution time, TCP handshake, and TLS negotiation for each third-party origin.

How It Works

Calculate the page load improvement from DNS prefetch and preconnect hints for third-party domains. Model the latency savings based on DNS resolution time, TCP handshake, and TLS negotiation for each third-party origin

Each component has a specific meaning:

  • DNS prefetch — The dns prefetch recorded for the patient or scenario being assessed.
  • Preconnect hints — The preconnect hints recorded for the patient or scenario being assessed.

Note: Interpret the dns prefetch benefit result against the clinical thresholds and context described above.

How to Use

Enter the DNS prefetch, preconnect hints for the patient or scenario you are assessing. Calculate the page load improvement from DNS prefetch and preconnect hints for third-party domains. Model the latency savings based on DNS resolution time, TCP handshake, and TLS negotiation for each third-party origin. Use the dns prefetch benefit result to inform your clinical assessment.
