Measuring slirp4netns Overhead Before Switching to pasta in Rootless Podman
Podman defaults to the slirp4netns user-mode network stack for rootless containers, which introduces context-switch overhead compared to kernel-level bridging. The pasta backend was added as a more efficient alternative, yet the performance gap varies with kernel version, CPU architecture, and distribution-specific netns or cgroup v2 implementations. Before
