I don’t believe your assertion. A quick check on the latest system-taxing application (aka a game), confirms the exact opposite. Even a cross-platform game, compiled natively for both OSes, runs faster on Windows in most cases. How do you square these observations with your assertion.

Which game? I don't agree with the position of the person to whom you are responding, but there's almost certainly much more optimization put into the Windows version.

  Why is “much more optimization” a limitation? What is preventing devs from optimizing the linux version? If the OS is more performant that should require less effort, no?

    My point is more that a game's performance is not necessarily a reliable way to measure relative performance of the OS. What game was it?

    Windows absolutely dwarfs Linux when it comes to gaming market share. Game developers will factor in return on investment and therefore a proportional amount time will be spent on optimizing the Linux port.

Games really aren't a good benchmark for overall system performance as they are generally optimized for Windows and non-Windows ports often receive a lot less attention. Also, most games are primarily stressing one thing - the graphics stack - and not I/O, scheduling, memory management etc.

I assume you are limiting your definition of "system-taxing" to playing games specifically? As other people have noted, filesystem performance is often better under Linux. I also will point out that at least some rendering tasks can be faster under Linux as well: http://blog.thepixelary.com/post/167616662857/improving-performance-of-blenders-cycles http://blog.thepixelary.com/post/167616662857/improving-perf... Just like with the filesystem performance discrepancy, this article seems to point out WDDM (Windows drivers) as the reason for this rendering discrepancy. And while we are on gaming (since I am a gamer as well!) when comparing games that run natively on Linux as well as Windows, Linux often has a performance edge over Windows: https://www.phoronix.com/scan.php?page=news_item&px=Win10-Linux-Vulkan-Early https://www.phoronix.com/scan.php?page=news_item&px=Win10-Li... Of course most games do not support Linux natively so in order to game on Linux you have to use WINE, Proton, or full virtualization to get a non-native game to run and this extra middleware layer adds overhead. But this doesn't mean gaming performance on Linux is worse than Windows; as comparing native-to-native performance shows.

  Using git as a filesystem performance metric is horribly flawed -- git was written from the beginning to perform perfectly on Linux. It's the most native linux application I can think of. (Not because it's using secret system calls, but because its design was vetted and performance tailored for Linux.)

    I didn't really specify git myself, but it doesn't seem like NTFS is a particularly high performance filesystem these days: https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.7-FS-5-Way https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.... https://www.makeuseof.com/tag/linux-transfer-files-faster-windows/ https://www.makeuseof.com/tag/linux-transfer-files-faster-wi... https://www.tomshardware.com/reviews/ubuntu-oneiric-ocelot-benchmark-review,3121-16.html https://www.tomshardware.com/reviews/ubuntu-oneiric-ocelot-b... https://superuser.com/questions/1124472/why-is-linux-30x-faster-than-windows-10-in-copying-files https://superuser.com/questions/1124472/why-is-linux-30x-fas... I also want to point out that just because NTFS isn't the fastest filesystem on the block doesn't mean it is a bad one. From what I can gather just casually googling it seems like NTFS emphasizes safety at the cost of performance at times. So depending on your workload and desired behavior NTFS might be the file system of choice for you. It's also worth noting that IF NTFS is intended to be more user-safe it sort of makes sense why may be the choice for the most common OS which aims to serve all users (not just technical ones).

So you benchmarked something that will to 95% be constrained by graphics drivers and platform specific optimizations. Afterwards you chimed in on a thread of people comparing file-system-performance constrained tasks, which hardly intersect with your test profile. Finally you provided exactly no information of your test setup, tested titles, or actual results in numbers, giving people who would nonetheless entertain you nothing to work with. Good job.
