I've been unable to locate anything other than changing the amount of machines to scan at once. When a scan is initiated, no matter if it's scanning 10 machines at once or 2 machines at once, our bandwidth spikes anywhere from 30mbps to 60mbps.
It also doesn't matter if the template is scanning for both installed & missing patches, it still spikes ridiculously high.
Are there any settings that I'm missing to throttle the bandwidth consumption?
