Abstract
Polling-based userspace storage stacks achieve great I/O performance. However, they cannot efficiently and securely share disks and CPUs among multiple tasks. In contrast, interrupt-based kernel stacks inherently suffer from subpar I/O performance but achieve advantages in resource sharing.
