Just to be clear, I'm not looking at the load average or CPU utilisation, since these measures are typically unreliable on modern CPUs (which vary their speed dynamically) let alone on VMs. I need a quick way to answer the following question: I've got this packet that I can drop without corrupting the video, should I drop it or not. Timestamp the packets at ingress time and drop anything droppable that's too old? Any other ideas? -- Julius
