I haven't done measurements on this, but my Macbook Pro feels much faster at swapping than any Linux or Windows device I've used. I've never used an M.2 SSD so maybe that would be comparable, but swapping is pretty much seamless. There's also some kind of memory compression going on according to Activity Monitor, not sure if that's normal on other OSes.
- thimabi 2y agoYes, other M.2 SSDs have comparable performance when swapping, and other operating systems compress memory, too — though I believe not as much as MacOS. Although machines with Apple Silicon swap flawlessly, I worry about degrading the SSD, which is non-replaceable. So ultimately I pay for more RAM and not need swapping at all.
- post-it 2y agoDegrading the SSD is a good point. This is thankfully a work laptop so I don't care if it lives or dies, but it's something I'll have to consider when I eventually get my own Mac.
- lynguist 2y agoNo it's true. Apple has hardware accelerated compressed swapping. Windows has compressed swapping. And Linux is a mess. You have to manually configure a non-resizable compressed zram, or use it without compression on a non-resizable swap partition.
