s6-overlay vs supervisord — Memory Footprint Comparison s6-overlay: Uses only 1–2 MB of RAM. Its service processes typically consume around 200 KB RSS each. Extremely lightweight, written in C, minimal overhead. supervisord: Consumes roughly 10–15 MB of RAM in real-world usage. Implemented in Python, so it naturally has a higher baseline memory footprint (≈8–10× s6-overlay).
