Sunkenland is an ocean-survival builder: players scavenge flooded cities, build floating bases, and defend them from raiders, all on a procedurally generated archipelago that the server keeps simulating. It supports a small co-op group by default, but the persistent world, ocean simulation, and structure tracking make RAM sizing the single decision that separates a smooth server from one that hitches whenever someone returns to a large base. This guide covers a clean setup and realistic RAM numbers.<\/p>\n\n\n\n
Baseline setup checklist<\/h2>\n\n\n\n
Sunkenland ships a dedicated server launcher. Get these fundamentals right before touching RAM:<\/p>\n\n\n\n
Install on an NVMe volume \u2014 the world writes constantly as structures are placed and sea state updates.<\/li>
Open and forward the game’s UDP port, and confirm it with an external port check; a half-open port shows as “server not responding” rather than a clean error.<\/li>
Set a server password even for a private group; public Sunkenland servers attract join spam that wastes slots.<\/li>
Choose the world seed once and back it up immediately \u2014 regenerating a world later does not preserve anyone’s base.<\/li><\/ul>\n\n\n\n
RAM sizing by slots and world state<\/h2>\n\n\n\n
Sunkenland’s memory use scales with both player count and how built-up the world has become. Budget using the second, larger figure once your group has real bases:<\/p>\n\n\n\n
Always leave 2-4 GB beyond these figures for the operating system. Running a Sunkenland server with no system headroom makes the whole node unstable the moment a large base loads. A common mistake is sizing to the fresh-world figure and then watching memory climb for weeks as players build; if you provision once, provision for the built-up column.<\/p>\n\n\n\n
CPU and network expectations<\/h2>\n\n\n\n
Sunkenland is less CPU-hungry than a large Minecraft network, but it still leans on a single simulation thread. Two to four fast cores will carry a small group comfortably; at 9-16 players with several active bases, four to six cores at 3.8 GHz or higher keep the tick stable. Network use is modest \u2014 inbound and outbound traffic is dominated by position updates and structure deltas \u2014 so a 100 Mbps uplink is ample for a casual group. What matters more than raw bandwidth is consistent low latency to your players’ region; hosting in a datacentre far from your group adds ping that no tuning can remove.<\/p>\n\n\n\n
Why save integrity is the real risk<\/h2>\n\n\n\n
Ocean-survival builders share a failure mode with other voxel games: a save write interrupted by a crash or a full disk leaves a partially written world file that will not load. Three habits prevent it:<\/p>\n\n\n\n
Never fill the disk.<\/strong> Keep at least 20 percent free so the server has room for temp files during a save.<\/li>
Rotate backups.<\/strong> Keep hourly, daily, and weekly copies, and test restoring one monthly \u2014 an untested backup is not a backup.<\/li>
Store a copy off the node.<\/strong> A second site or object store survives the exact failures that take your primary down.<\/li><\/ul>\n\n\n\n
Tuning for smoother sailing<\/h2>\n\n\n\n
If players report hitches when approaching a large base, the cause is usually the server loading and saving structures as players come into range. Options that help:<\/p>\n\n\n\n
Reduce the maximum number of placeable objects per base where the config allows it.<\/li>
Split a sprawling community across two islands so no single base becomes a hot spot.<\/li>
Move saves to NVMe and enable frequent small autosaves rather than rare large ones.<\/li>
Pin the server process to fast cores so save IO threads do not compete with the main simulation tick.<\/li><\/ul>\n\n\n\n
A realistic tuning workflow<\/h2>\n\n\n\n
Rather than guess at settings, tune against observation. Start the server with a modest spawn multiplier and watch memory and tick time for a full session. As your group builds, re-check every week. When tick time creeps up, cut the heaviest setting first \u2014 usually creature spawns \u2014 before adding hardware. If RAM climbs but the CPU is idle, you have a memory leak or an oversized world and should prune, not upgrade. If the CPU is pinned while RAM is comfortable, raise clocks or move to a faster core. Following that order keeps you from buying hardware to solve a configuration problem.<\/p>\n\n\n\n
