From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

In my experience, every computer is faster with Linux than with Windows. But if this measures just the processor performance on similar tasks I guess it's news.
I think it comes down to the culture. A minuscule improvement to a file system is big news in the Linux community. There's also lots of academic interest in the performance critical parts of the kernel that you just can't emulate with a closed source model. Is anyone writing papers on how to obtain a 2% improvement in the task scheduler on Windows?
Linux dominates the server market, so even small improvements matter when you're talking about a server farm with thousands of machines or the latest supercomputer. Many, many people care about the scalability of Linux. On Windows, we say: NTFS? It's good enough. The user won't notice on modern SSDs.
A lot of the software components under the hood in Linux are replaceable.
So you have a bunch of different CPU and disk IO schedulers to suit different workloads, the networking stack and memory management can be tweaked to hell and back, etc etc.
Meanwhile Windows Server 2022 has...... ?
Consequently battery life tends to suffer on Linux vs windows. Especially on newer hardware before people figure out how to manage performance and battery life.
Usually, applying the same tricks that Windows does, its not true.
But by default, mostl Linux ditros dont do something special for having performance managing.
But actually. Windows does neither, at least the pure Vanilla form. Its a huge difference when using my Levono Ideapad with the preinstalled Windows versus Windows that is reinstalled Vanilla without drivers. Then Linux is more plug and play and better at this job than Windows.
Maybe they do it differently on ideapads. But on all of the modern thinkpads I own the all install at set up the same power profiles and dynamic tuning that the factory image does. Factory install vs fresh install performance is the same on these machines once windows update has done it's thing. Even the random POS HPs will do the same thing.
Older machines yes absolutely.
