    smbd using lots of CPU


    I'm curious why smbd is using so much CPU time.

    When I copy a file from a Samba share to my Windows box, it typically uses about 15% of the CPU time (according to top). This is on a 2.66ghz celeron.

    That seems like an excessive amount of CPU time to read from a disk and transmit across the network. I know Windows doesn't use nearly that much CPU time when files are copied from shares...

    Just curious and hoping maybe there's a fix.

    Look if DMA 5 is enabled for your harddrive. Samba uses loads of CPU time if DMA 2 is enabled.

    I have 3 hard drives. When I installed linux, I created a single logical parition that covered all 3 (with /boot in a separate partition)

    2 of the drives are using udma6 and 1 uses udma 5.

    If you have raid configuration based on software raid than it will use more cpu time as Hardware raid.

    It's not RAID. I simply have the drives linked together as a single logical partition.
