> Swap still absolutely sucks no matter how fast the SSD

People always forget that Apple does realtime compression on data that's in RAM allowing more things to fit in RAM; it also effectively increases the bandwidth of the SSD.

Nobody forgot anything, and I certainly didn’t. You can tell when you hit swap, and it doesn’t matter what Mac OS X is designed to do, when you hit swap, you hit swap. When you’re hitting swap a lot, you’re hitting swap a lot.

Windows 10+ and Linux also have memory compression, though I don't know how the implementations compare.

Although, I guess Windows 3.1 and 95 users enjoyed it first thanks to this extremely high quality third-party implementation!
