From be2a7898e9de236da7c42d1fb37a5a2017ac192b Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Mon, 21 Feb 2022 13:35:45 +0100 Subject: test: Add demo for Podman with pasta ...showing setup steps, some peculiarities as --net option, and a general side-to-side comparison with slirp4netns(1), including "quick" TCP and UDP throughput and latency benchmarks.
