pong

Pong is a simple CLI program that I use to check latencies between different AWS regions. It's written in Zig and rendered with the excellent libvaxis TUI toolkit.

Features

• Zero-copy rendering pipeline with per-frame stack buffers to keep latency stats allocation-free.
• Concurrent HTTP HEAD probes across AWS regions with per-worker threads and shared atomic coordination.
• Rolling percentile/variance tracking without heap churn by using fixed-capacity ring buffers.

Installation
