You don't have to disable it at all if you don't want to. Some, like me, do because we aren't interested in what Norton considers to be high resource usage; in 99 out of 100 cases for me it reports high resource usage of something I want to use a lot of resources, like a demanding game for example, or something that I would rather have use a lot of resources and be done fast rather than use less and take forever. It's not a security-related feature, and I use Norton for security, not for performance alerts. But if you want the feature and feel that it is useful, go ahead and keep it enabled.
