"We've just moved some of our software to run on Linux instead of
Windows nodes and the CPU usage increased significantly.

Windows: 41mc
Linux: 226-231mc
Factor of 5.5x

I added new traces and counters for linux and windows in comparable idle
situation.
From the counters I can see now that CPU usage is:

windows: Average = 0.2%.
linux: Average = 1.13%"

https://github.com/dotnet/runtime/issues/71921

I got similar results when Linux consumed 21% of the CPU just moving a
Thunderbird window around, but Windows used no more than 6% doing the
same thing.

Which is almost certainly due to better video card drivers on Windows. No one
cares about video performance on Linux, since 99% of Linux usage is as
DB/App/Web servers. Most of those are headless. No video card needed.

Windows has better video performance because Windows is the front end. Linux
is the backend. Both for obvious reasons.

Not to mention all the games that run only on Windows, which demand great
video performance. If/when Linux ever becomes a serious gaming platform
(which, let's face it, has about the same probability as Windows becoming a
great 24/7/365 backend server), high end video card makers will start caring
about video performance on Linux.

I game exclusively on Linux using proton, through SteamPlay, on Steam.
My games are _Elite Dangerous Odyssey_ and _Starfield_.

Instead of using Windows' DirectX, proton uses the Vulkan-backed DXVK,
which can be faster than Windows.

Haven't played Starfield in a while, but EDO is capped at 90fps, which
is fine for my 60fps 4K monitor. I don't think the NVidia proprietary
drivers are a bottleneck.

I've got a Thinkpad T480S, dual boot Windows 10 and Debian 12, and on
the occasions I boot into Windows, it fires up the fans, even just
booting it. Whereas on Debian, fans rarely get going. Don't know
exactly why, but both OS seem to run well, just that Debian (with FVWM
as the Window Manager) doesn't seem to stress the machine. I use the
same machine for work, and even then, doing light tasks the fans spin
up frequently.

:-D

Not to mention the test is from 2020.

And how did he get that awful tearing? Was Doof running Linux in a VM?

I'm QUITE sure the results today will be similar.

To test I'll have to install Linux in dual-boot.

I got that awful tearing because FOSS crapware programmers are let loose

Most likely I was using the proprietary nVidia driver for Linux and Windows.

Either way, Linuxfux will make some lame excuse.

They already do. nVidia has been releasing parity drivers for Linux and
Windows for years.

That was right something like 20 years ago. But recently games have
really improved on Linux. And games need video cards. It's probably one
reason why Linux Desktop improved recently (the other reason is that
Indians are really using Linux for real now)

Your information are really outdated on the subject. So your previsions
are bad.

I don't know and I don't care. What I know is I see a lot of people with
an old computer running Windows with difficulties because it's too slow.
And when we put Linux on it it gives life back to the computer.

So, I already see you have some issues with Linux which looks like you
are the only one in the world to encounter. I have no explanation. But
generally, from my experience, Linux is faster than Windows.

All I know is that my fans run a lot louder and my computer is hotter when I
try Windows than when I'm running Linux.

Linux has to work a lot harder to run Windows games. They're native to
Windows. So they should run better on Windows.

My experience as well when using my Dell computers. So I have trouble
believing Windows is more efficient.

It definitely does. Even if Windows was faster (it's not) they choke down the
OS' speed with calls to "home," unwanted ads and virus checking.

Linux is always faster on my "trailing edge" computers.

Apparently, they perform better in Linux if the GPU is made by AMD,
simply because of how optimized the open-source driver is. YouTube has a
number of tests showing this. For NVIDIA though, the performance is a
little worse.

Windows has its advantages, but I wouldn't call it efficient either. Even
if it were, the reality is that Windows does not afford you the same kind
of control over your hardware that Linux does.
