High-precision TCP & TLS handshake RTT and socket throughput benchmark
A high-precision TCP 3-way handshake latency, TLS handshake round-trip time, and socket throughput benchmark utility for Linux. A lightweight Linux alternative to Sysinternals PsPing for measuring microsecond connection latency, jitter, percentile distributions, and loopback or LAN stream bandwidth.
Key features:
- Measures TCP 3-way connect RTT and full TLSv1.2/TLSv1.3 handshake latency using nanosecond monotonic timers (perf_counter_ns) with configurable warmup iterations, probe counts, and intervals.
- Calculates comprehensive latency statistics including Min, Avg, Max, mean consecutive jitter, standard deviation, and P50, P90, P95, and P99 percentiles.
- Visualizes live per-sample round-trip time series charts, latency distribution histograms, and multi-endpoint session comparison tables.
- Includes a built-in TCP echo and sink server for testing local loopback or LAN socket stream bandwidth (MB/s and Gbps) and application-layer echo round-trip time, with CSV and JSON report export.
