Jyrgen Posted December 10, 2020 Share Posted December 10, 2020 Hello everyone! I am writing to learn, if anyone has any information or experience to see, how much RAM would my server need, to host all 9 maps. Our server player base is small, but we like exploring around in crossark. Even most servers will be empty at most times I understand ARK has no automatic pause or RAM optimization mode. Could someone tell me how powerful server would I need to pull something like this off? Thanks! Link to comment Share on other sites More sharing options...
zero064 Posted December 10, 2020 Share Posted December 10, 2020 My server (usually 1-6 players on at a time) runs a six-map cluster no problem with these specs: Ryzen 3200 32GB RAM 1TB nvme (500GB would be more than sufficient) I'm sure 9 maps would be fine as well, as my CPU usage rarely goes past 50% and the RAM usage tops out around 20GB with all 6 maps running. I also have a Minecraft server running. Also, keep in mind that you can shut down one or more maps if you don't plan to go there for a while. If your situation is one where you're with friends/family and you all move from map to map together, it'll be rare to need them all running at once.

Larkfields Posted December 10, 2020 Share Posted December 10, 2020 There are two clusters here... "ShooterGame" is one cluster, and "ShooterGame(2)" is a second Cluster. Ragnarok consistently uses more RAM than the other maps. Link to comment Share on other sites More sharing options...
Volunteer Moderator invincibleqc Posted December 10, 2020 Volunteer Moderator Share Posted December 10, 2020 If you launch your servers with the -nitradotest2 option, it will limit the tickrate to 3 when there are no players connected. This can have a noticeable impact on CPU as well as memory for large worlds since there will be less calls per second (less computation/memory allocation, etc.). But as its name clearly state; it seems to be an internal test so use at your own risks. Link to comment Share on other sites More sharing options...

Do you have any contact with WildCard to request that flag as an option for unofficial servers please? Link to comment Share on other sites More sharing options...

Seems that all you would need to do is add it to your existing startup arguments for unofficial servers. I'll give it a test later. @Jyrgen Nominally you would want to allocate 8GB per server with 2GB overhead for the OS. Our group was running 8 maps with a few players on our server with 64GB RAM. CPU and RAM usage when idle was about 40% and 70% respectively, so we didn't have much overhead at all when things got busy. We have since reduced our number of servers to 5, and will hold off on turning the others back on until we add more RAM. Link to comment Share on other sites More sharing options...
Larkfields Posted December 11, 2020 Share Posted December 11, 2020 I'm assuming WildCard build a specific version of the Ark server for Nitrado. Link to comment Share on other sites More sharing options...

I ran a quick test on a VM running the same legacy save twice; one instance without and another with it and here was the usage without players: Link to comment Share on other sites More sharing options...

IanHighlander Posted December 11, 2020 Share Posted December 11, 2020 This is with seven of my nine servers running with a couple of players on (very small community of players) I can comfortably run all nine plus a 7 Days to die server at the same time. This is with it running Island, Ragnarok, Aberration, Extinction, Valguero, Genesis and Crystal Isles HP Z820 workstation, dual E5-2643 Xeon processors (total 8 cores, 16 vcores), 64GB RAM, running the Ark servers on an 8 disk RAID 6 array of Western Digital black disks.

SylenThunder Posted December 12, 2020 Share Posted December 12, 2020 I did notice an increase in RAM usage. Also it had little effect on the Abberation map. That one went from 4.9% to 5.2%. Before After Link to comment Share on other sites More sharing options...
Larkfields Posted December 12, 2020 Share Posted December 12, 2020 Sylen - from the figures you posted, it looks like your RAM usage has gone up by more than 10x ! How many people were logged on when you took those screenshots? Every player has a memory and CPU footprint. Link to comment Share on other sites More sharing options...
Larkfields Posted December 12, 2020 Share Posted December 12, 2020 With no users online, -nitradotest2 has saved between 50MB (on Extinction) and 600MB (Crystal Isles) on a cluster I run for friends and family. Link to comment Share on other sites More sharing options...

How many people were logged on when you took those screenshots? Every player has a memory and CPU footprint. There were zero people logged in at those times. Each set of numbers was taken 5 minutes after the server was started, so it had time to settle into whatever. I did it at 4am, so no one was around. That's our normal maintenance window anyway. What's interesting though is that the amount of RAM used in the second shot with the argument, is what the server looks like when it's active with a few people on. So it may just be a trade-off for lowering CPU use where it's holding more data actively in RAM. Link to comment Share on other sites More sharing options...
Xenithar Posted December 12, 2020 Share Posted December 12, 2020 Each map has a unique memory pattern. I host all nine, a 7 Days server, a TS3 server, and some other stuff. I also have two 56-core Xeons and 128GiB of ECC RAM on a pair of BTRFS RAID10 setups. With that said, here is what I regularly see. The Island - 4-6GiB The Center - 4-6GiB Scorched Earth - 5-8GiB Ragnarok - 4-6GiB Aberration - 4-8GiB Extinction - 4-8GiB Valguero - 4-8GiB Genesis - 6-9GiB Crystal Isles - 4-8GiB Do note that per-core power is FAR more important here. More cores not so much. Memory for what these maps are seems reasonable. Oh and for clarification, I run S+, Classic Flyers, and Additional Lighting on all of these servers. Nothing else. We have maybe a dozen players per server in the evening when usage goes up. Link to comment Share on other sites More sharing options...
