Would netflix benefit if zfs was modified to use a unified cache to make zero-copy possible?

- drewg123 4y agoPossibly. Remember the goal is to keep data read from the drives unmapped in the kernel address space, and hence never accessed by the CPU for efficiency. So we'd have to give up, or at least alter, zfs to not do checksums each time a block is read. The most interesting use of ZFS for us would be on servers with traditional hard drives, where ZFS is supposedly more efficient than UFS at keeping data contiguous on disk, thus resulting in fewer seeks and increased read bandwidth.
