This registry setting that controls the frequency of these checks (in seconds) is PollingIntervalSeconds of DWORD type, and its default value is 30 (decimal). This process may have a significant performance impact on large environments with a large type space and frequent configuration changes. In such situations, the recommended value is 120 (decimal).
This setting can bring a significant improvement in the overall performance, but setting the value too high can mean a delay in changes being loaded into the Health Service on the management servers, and this could cause delays when implementing new workflows, overrides, management packs, or discovered inventory.
