      All four cores at 100%? We don’t see that kind of spike when we open some other application right? Is it the experience of everyone? Or am I wrong in this?

        I mean, maybe. Imagine averaging the usage over a single instruction cycle. Whatever ran that instruction is using 100% of the processor for that time period.

        That first data point is simply invalid. Ignore it. Monitoring software usually report some kind of statistic (mean, median, min/max, etc) taken from measurements over a period of time instead of the instantaneous value when the report is updated. But they can’t do that for the first data point when the application is launched because there’s no time period over which to measure it.

        Unless bottlenecked somewhere else, we would want to see 100 % with everything that takes more than some milliseconds.

          This is the real answer. Other apps might be bottlenecked by IO so the CPU doesn’t work as hard. Get faster disks, the CPU will see more use. Since top is so small that it loads into memory almost instantly, and has no need for further IO, the CPU is free to spin all the way!

          People get worked up when CPU usage is high, but unless there’s a resource leak somewhere, that just means the computer is working at full efficiency.

          It’s like when the boss walks in so everybody becomes visibly busy. Never want to look like you could be the couple pennies shaved off the budget when management bonus calculation time comes around.

        Absolutely. That’s why race to idle is a thing. As soon as the CPU is fed cycles it races to complete the task as quickly as possible. When the program first launches and starts monitoring the only thing it knows is that it was just doing something. It hasn’t had a change to not do something. It’s now completed its race and now it’s able to relax for a second and idle.

        It’s going to be an artifact of the data collection method. The sample size is extremely small and taken during the period where top has never stopped running.

    Same happens opening Windows Task Manager, my older server rig used to lock up frequently, stalling programs like Home Assistant, and the only thing I had to do to fix it was remote in and open Task Manager. CPU usage dropped to between 70% and 30%.

    This, incidentally, was why I was convinced I needed better hardware for a dedicated Proxmox rig. I was very wrong. With Windows, I can barely run three services (HA, AgentDVR, Emby) alongside their stupid NTFS scan and antivirus. With Proxmox I can run 20 services with no issue. CPU is usually 60%-70% with everything.

      I’m running like 18 machines inside of hyper-v and don’t have that problem. Were you using a consumer version of windows or something?

          Yeah that explains it lol. Fwiw, if you ever want to try windows as a hypervisor again, server editions can run for 180 days on a trial license and you can buy legit product keys from dodgy resellers online for like $10. I’d go that route for running any kind of real services.

              They’re MSDN keys, so they’re valid and never stop working. That’s worth $10 to me. It’s not illegal for me to buy them. It’s illegal for the Polish dude to sell them.

    Same, but if you haven’t aliased top to btm --battery you’re not really living
