Re: [zfs-discuss] poor CIFS and NFS performance

If you're dedicating the disk to a single task (data, SLOG, L2ARC) then absolutely. If you're splitting tasks and wanting to make a drive do two things, like SLOG and L2ARC, then you have to do this. Some of the confusion here is between what is a traditional FDISK partition (p
