Sorry for even asking
(lemm.ee)
Or is it only me?
top immediately upon starting:
TOP averages out readings from the last few seconds. If there aren't enough samples the displayed values can be… off
Well it does make sense that the CPU has to work a bit when loading a new program.
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?
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.
Lim t->0 x/t =infinity when x>0
Math - not even once.
I paid for all the cores, I'm gonna use all the cores!
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.
Top revs the engine as a test /s
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.
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.
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.
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.
btop ftw
btop is nice and I use it sometimes; but htop, my beloved, doesn't complain about the screen size being too small. And it's more visual for me anyways.
yeah htop is useful on a phone
btw to format inline code blocks, put a single backtick on each side of the code, like this: btop.
Can't wait for zztop
How dare you call my laptop a "phone" /s
(btop on the left)
Also, thanks for the tip, I just used voyager's formatting cause I was on my phone :'D
That's a very nice desktop.
I like the color scheme of the buttons in the top right
glances Btw
It runs on Windows
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?
Yes aha, Windows 10 Home, 22H2 update. Only Windows OS I owned and this was before I tried Linux
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.
If you are going to use a illegal copy of Windows don't spend $10
Just use the mass grave scripts
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.
You guys hate GUI, don't you?
No, but I don't see the value in using the GUI for something that can be gotten with less complexity and overhead.
You are allowed to use GUI and CLI tools
You're dyslexic, aren't you?
Yes
Ho y te?
