Front-window bakery material. Catches the eye, delivers the goods.
Summary
Fastrace is a high-performance, dependency-free traceroute implementation written in pure C that significantly outperforms standard traceroute utilities. It achieves ~20x faster tracing through techniques like non-blocking sockets, batch I/O, concurrent probing, and optimized syscalls. The tool provides clear output, detects load-balanced paths, and maintains minimal system call usage while being completely dependency-free.
Key quotes
· 4 pulledFastrace is designed for speed. By using non-blocking sockets, batch I/O, concurrent probing, and optimized syscalls, it completes traces significantly faster than the standard traceroute utility.
fastrace completes the trace ~20x faster while providing richer output including load-balanced path detection.
Fast, dependency-free traceroute in pure C. Minimal syscalls, clear output, significantly faster than standard traceroute.
Benchmark: google.com - fastrace: 13 hops, ~1.5s, 74.4% response rate vs traceroute: 11 hops, ~30s
