There's alot of room for adjustments/experimentation within the posix-like OS space; Linux is not always the best vehicle for this experimentation (witness various threading/ipc/scheduling differences with others, security protections, etc. that a) exist and/or b) have been imported/emulated in Linux )
- spijdar 6y agoI thought about this a while after this, and yeah, I'd agree. Although as far as scheduling and IPC goes, I'd say this is less about "raw performance" as taking a chunk of CPU cycles and better utilizing it. So a VM running under Linux/KVM could experiment there in useful ways. There are still new/tweaked ways to manage/divide raw hardware, though. Stuff like trying to reduce UI latency which would be hard to do through a PV interface and needs bare metal.
