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.

Some generally older software has buggy multi threading implementation, and forcing its threads to execute "interleaved, but never simultaneously" often improves stability or even completely hides the issue.
Also I know some games used to have big performance issues if they had too many hardware threads available, but I don't know why exactly
There's also modern CPU structure, where there might be a performance hit if you involve cores that are attached to a different cache or don't have direct access to memory. Threadripper ran into that sort of thing.
