    In FreeNAS 8.0.2, I found it is very fast to "Cut" very large file from one place to another place in the same nas (Operator is done in windows 7). But it is very slow to "Copy".

    The "Cut" looks like directly do "Cut" in nas. But the "Copy" looks like: Copy data from nas to win7, then forward these data to nas.

    I think it is a waste of time. If the nas can understand the source and destination are both in nas, then it should do a local copy, no need to go through the network.

    Thanks

    That's a CIFS thing. Nothing the NAS can do anything about by itself.

    A cut just updates the file pointer, a copy has to make a complete copy.

    Now if you want to see REALLY slow, try cutting/moving a file from one dataset to another on the same volume..... then you'll know what slow is.... I don't understand that...

    The "slow" I mean is it copys data through network (nas --> win7 --> nas), not just a local copy. The speed is depend on the network speed. This is the problem.
