because ram is expensive compared to disk.
Ram is normally fixed compared to disk
by storing not-used but still needed pages on disk, allows for much greater performance with less resources. for example it allows a bigger VFS cache.
- radisb 2y agoSo hypothetically, if ram was as cheap and easy to add as storage, swap would not make sense?
- KaiserPro 2y agodepending on OS and upper limit, yeah RAM all the way. But I suspect the kernel doesn't think like that. I know that OSX does things differently, so perhaps there are better ways
