    I've got a couple of older NAS boxes - Thecus N5200B Pro (5x 2TB, RAID-6), Thecus N7700+ (6x 1.5TB).

    New Mac Pro 6,1, although I've used these NAS with my old Mac Pro 1,1 (2006), Mac Mini 6,2 (Late 2012), and older Macbook Air.

    Lately I've noticed when I connect to the N7700+ AFP share, the CPU on the NAS jumps to 100% and sits there for quite a while.

    I assume it's related to a Finder view setting like "Show item info" or "Calculate all sizes", but as I've played with them I haven't quite figured out the correlation.

    Has anyone else encountered this?

    Could it be related to Spotlight indexing the drive?

    Maybe. How can I tell if Spotlight is enabled for that network drive? I added it to the Spotlight Privacy tab, just in case.

    I also recently started using that network drive for Time Machine backups, although they aren't running when I see the problem.

    There's very little network traffic.
