Not sure if this is normal or not. Running 2.3.16, but noticed this was 2.2.x as well. I had originally ordered the bundle from Bluecherry so got the PCI 4 port capture board at the time. I currently am using three IP cameras, one 720p and two 1080p. The CPU is a dual core i3-3240, and I notice using top, bc-server is using 150%+ of cpu usage most of the time even with no clients connected. I had thought that the capture board was supposed to offload the CPU, but not sure if I misunderstood or this is working as expected.
