dev.perf-tcp-handshake Calculator
Calculates TCP handshake overhead, connection establishment time, and the benefit of connection reuse or HTTP/2 multiplexing in a application performance engineering context. TCP+TLS handshake adds 2–3 round trips of latency — a 100ms RTT path pays 200–300ms just to establish a new HTTPS connection before any data transfers.
Inputs
Rtt
Reference formula or conversion factor shown for context.
Tls
Reference formula or conversion factor shown for context.
Conns
Reference formula or conversion factor shown for context.
Results
handshake latency
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
total overhead
The combined total across all inputs and components.
TLS cost
The total monetary cost computed for the given inputs.
