Pong is a simple CLI program that measures and compares AWS region latencies in a terminal table. This version is written in Rust with ratatui and crossterm.

• Concurrent HTTP HEAD probes across AWS regions (one worker per region).
• Live TUI table sorted by lowest average latency.
• Rolling min/avg/max/stddev/p95/p99 stats with fixed-capacity ring buffer percentiles.
• Optional warmup delay before sample collection.

cargo run

With warmup:

cargo run -- --warmup 5
