Policy

CPU throttling type

This policy setting determines whether the maximum percentage CPU utilization permitted during a scan applies only to scheduled scans, or to both scheduled and custom scans (but not real-time protection). The maximum CPU utilization limit is also referred to as CPU throttling, or a CPU usage limit. The default value for this policy setting is True, which means CPU throttling is applied only to scheduled scans. If you either enable or do not configure this setting, CPU throttling will apply only to scheduled scans. If you disable this setting, CPU throttling will apply to scheduled and custom scans.
