Large servers use up to 150%. 128 tick is a significantly higher update rate than almost any other game today, for this reason. It takes a TON of CPU to do it.

Well I cant even run a 32 DM 128 tick server on a E5-2687WV2 without it hitting almost 100% CPU.

In case this would lead to notable performance improvements, I'd rather have the devs use some recent SSE instructions wherever possible at the cost of stopping support for some old CPUs. Like, seriously, "scrds dares to take up to 55% of one core of my slowly clocked, 8 year old CPU, when I'm running a 128 tick server with 9 players"? That's good comedy. If you like your players and want to treat them well, host on decent hardware and have realistic expectations.

    CPU usage you are seeing is expected on something that old.

        And yes up to 55% with 9 players on one server with tick 128.
        And its locked to one core.

        Its Debian.

        So it's hitting 55% usage with 9 players on at once? What's
        the tickrate. Also, what CPU is it? Are you locking it to one
        core via affinity or letting it core swap?

            Clock speed isn't everything, but it's important.
            Architecture is also extremely important. An E5-2609v2 @
            2.5GHz came out in 2013.  A Pentium 4 @ 2.5GHz came out in
            2002. They're both 2.5GHz but nowhere near the same in
            architecture. OS/Distro also plays a role. Tickrate is
            also a large part of it. You can run more slots on the
            same server with lower tickrates.

            Also, when you say 55% CPU, what is that number coming
            from? If it's the "stats" command that's nowhere near
            accurate. If you're using some form of task manager
            (windows task manager, top, etc) then check if that "55%"
            is 55% of the core or 55% of the entire CPU.

            What OS/Distro?

                        Thats insane right? How can one small server
                        without heavy mods take up to 55% CPU?

                        Is there anyway to lower the CPU usage without
                        lowering tickrate/rates/slots?
