Strange Finder cpu usage!

Selecting a movie in a Finder window leads to a constant cpu usage by the Finder only of about 10% according to top run from terminal.



I mean just selecting it, not playing the movie inside a Finder window. I did this right now and switched to IE while top shows still 5-8% during the last minute.



Now deselecting the movie.....Finder falls to zero, nada, 0% exactly.



Strange.



Anyone with an explanation?

    I get the same behaviour.



    Could it be that the finder is constantly buffering the .mov for smoother playback?

    This only seems to happen to me when i select a movie in column mode. Assumably the cpu usage comes from generating the preview. Having a movie selected in list or icon mode does not seem to take any cpu time.

    So it must be generating the preview in an infinite loop because this seems never to stop. (Tested for 10 min.) The preview usually gets displayed in a few seconds.



    The Finder is a heap of mystery and still half baked stuff it seems to me. In certain situations it also leaves tracks of borderlines behind in underlying windows....

    Well, I just tried this for myself and got a really strange behavior.

    When selecting a movie in column mode, the cpu usage of the Finder jumps to about 25% for a second or two (depending on the size of the movie), then just having the file selected the cpu uses only .9 to 1.8% cpu. Here's the strange part.: When playing a movie in column view, the Finder cpu usage jumps to anywhere from 90% to (and I'm not lying here) 130%!!!!. :eek: :eek: :eek:

    How can something hog 130% of a processor?

    Riddles are abound tonight.

    Simple: you have dual processors (200%).

    hehehhhe.



    starfeeltX is correct.



    I really do think it's buffering, though.
