The CPU usage is really hard to describe. #137

The fewer bots on your server, the less resource consumption.

The problem is that no matter what kind of CPU, no matter whether the CPU is strong or weak, I use ARM64 and x86_64 CPUs and there is always one CPU core that is 100%, which is outrageous.

Do you have any real trouble? I don't think high CPU utilization is abnormal. It means your hardware is working, that's all.

High CPU usage is really not a problem. The problem is that no matter what kind of CPU it is, there is always one CPU core that is used at 100%.The htop command checks that there is always a CPU core usage of 100%.

Maybe try a profiler: https://learn.microsoft.com/en-us/visualstudio/profiling/cpu-usage?view=vs-2022 ?

I'm running a server with 2500 bots and I do not have your issue: image

Thread-wise, the only settings I adjusted: ThreadPool = 8 MapUpdate.Threads = 8

Lastly, I noticed you're running into swap, which is extremely bad for performance in general.

I'm running 2 realms on a single system, one does not have playerbots but has preloaded grids and creatures set as active, and I don't run into this issue. I'm basically putting as much load as I can on the system, which is aarch64 hosted by Oracle, and it's still not maxing out.
