I'm not a Windows hater, but one of my long standing gripes about Windows is that it just seems to have terrible multitasking compared to OSX.
I'm sure there are reasons but it just seems utterly symbolic of Microsoft that they never managed to get Windows to multitask in a rock solid, smooth and reliable way like OSX.
See for example Con Kolivas' famous rant about how Linux schedulers were ignoring the interactivity requirements of desktop usage, and resulted in a terrible experience with constant tiny freezes.
And OS X certainly doesn't have anywhere near all the kick ass monitoring tools that Windows as, such as the ones shown in this article.
It's quite impressive.
It certainly helps that Intel really likes Windows, but I haven't seen Mac users complaining as much as Windows users do, so, it may be for lack of demand (and the bundling of dtrace, for ages).
Using both Macs and Linux laptops, I'm sometimes shocked at how the Mac sometimes locks up when the Linux machines degrade much more gracefully under heavy loads. I never dug too deep into it, but it feels like it's something with HFS+ under heavy IO. I hope APFS fixes that.
I've been a Mac user for 7 years now, my latest greatest MacBook Pro halts for a few seconds when I connect an external monitor and everything is frozen and unresponsive, like I'm looking at a screenshot of the system
OS multitasking is still usually shit...
