    Hmm, I'm not sure what can be done to speed up ls -l -- it's doing a
    getattr on the files, so it generates a lot of message traffic.

    It seems like something must be wrong with the samba server process, as
    it normally should respond instantly with a new socket. I'm not too
    clear on what happens on the samba side when you need a new connection
    -- smbfs just sends the server a signal and waits for an ioctl call.

    Any way you could turn on debug logging on the samba side and see what
    happens during these events?

    Regards,
    Bill
