You may be right that our application does not qualify as heavy duty. The CPU usage is not maxed out, although LV seems to use only 4 of the 8 cores. The memory usage is quite low, which I thought may be due to limitations of the 32 bit software. The vision applciation is capturing video, doing some processing (averaging, background subtraction, text overlay), displaying the live video, and recording an avi file with lossless compression. As I recall, the incoming video is made up of 1080x1080 pixels 10-bit, B&W coming in at a frame rate of 30 fps. We can't have the system drop frames while it records approx. 5 minute long video segments. It runs 24-7. Our first PC had a hard drive failure. The current PC seems to be having memory leak issues, which we think may be caused by cloning. We are starting over with a fresh install of everything. Perhaps I can start a new thread regarding these problems once we get the software installed and start running tests.
