    Multi-Core support?

    As the title says, are we ever going to get multi-core support for dedicated servers?

    Currently I'm running the dedicated server on an i7-7700k @ 4.5GHZ because I need the extra clock speed to make up for the lack of multi-core support. Sitting right beside my desk is a 40-core Dell PowerEdge but since it has a clock speed of 2.2GHz, a single core is not sufficient for the game.

    As this game grows I think we will see a much larger demand for this, and if it doesn't happen, I worry that people will lose interest.

    Unity does already support multicore. I'm running several servers on a Dell PowerEdge R710 without an issue. It works less effectively on AMD chips, but so far has been pretty good on Intel.

    My AMD 8320 based dedicated server has been running silky smooth for me (and I didn't even pay a dime for it ). Although, I haven't tried a large number of players yet, only 3 so far. But not a single hitch, and CPU sits at around 10 - 15% most of the time. Even back when I only had the ancient AMD X4 965 quad core CPU... ran fine with 4 players, though it did hitch a little bit when all four of us would separate and explore, but that could have been due to the old hdd I had not being able to keep up cuz that CPU at the time only reached a maximum of around 80%.

    Unless you're trying to get more than a dozen players on your server, I don't think anyone needs to spend much money on a server to get it to run smooth; just properly good internet, basic SSD, 8GB of ram or better, and a high end quad core or better (which these days doesn't cost much).

    So I understand how running multiple game servers would utilize multiple cores, but are you saying that a single game server can utilize multiple cores? Because in my testing, I only get utilization from a single core when running one game server.

    In my testing, it would use multiple cores when the need presented itself, and otherwise would only use one. I tested in a16 with one server running, set max spawn at 400, and bloodmoon count to 64. We then got 6 people on and had a party. It utilized at least 12 of the 24 cores for the dedi. (might have been 16, but I was trying to defend the base at the same time.) It went great until we hit the max entity count and crashed Unity.

    I haven't set up a similar test with a17, but I haven't seen anything different about how it behaves. If one of my servers gets busy, I start seeing multiple cores active.
