ARK: Survival Ascended is memory and single-thread bound, so dedicated server performance depends on high clock speed CPU cores, sufficient RAM headroom for the map and mods, and fast NVMe storage for save writes. This guide covers recommended RAM per player count, mod load order and update handling, autosave interval tuning to reduce stutter, log analysis for out-of-memory crashes, and cluster configuration for transfers between maps. Apply changes one at a time and restart the server between adjustments so each change can be measured against tick rate and save duration.
