Please let me know if you have any questions or concerns in regards to this information. You can also review the best practices documentation for optimum ODS configuration: Please review the following articles that go further in depth in regards to these concepts: However, as described, high CPU during ODS is expected by design, and there is not much that can be done to make a dramatic difference in scanning.

We recommend that you look towards these config changes to assist in lessening the impact of the ODS. Please keep in mind that this will not eliminate increased CPU consumption by ODS, but can increase the frequency and speed at which resources are handed off to other processes via priority leveling of the OS. The second change (as you state you have implemented) is to change system utilization from normal to low in order to set us at the lowest priority for resource allocation. If there is a large number of archives on a system, this scenario is more frequent and can create significant impact to performance and scan duration. This extended time to scan the large archive files prevents Microsoft's priority allocation for resources from handing the processing power to other processes that request it until the entire archive is scanned or the default 45 second timeout is reached. This is considered to be a very minor to non-existent security risk because all files inside an archive are scanned when the archive is opened or extracted, making scanning these files redundant, because OAS will scan the archive if it is accessed or opened at any time and scanning them during an ODS can take some time. The first configuration change that can assist in making significant changes to scan duration and performance is disabling scanning of archives during ODS. For this reason, we advise that your ODS be scheduled at a non-peak business hour, or on weekends, in order to limit the impact to the end user. Windows process prioritization will provide the scanner with all of the available resources for this reason, until a process with higher priority requests use where it will temporarily hand it off to the requesting process before handing it back to the scanner. High CPU during ODS is expected behavior and is by design in order to get scans completed as quickly as possible and lessen the window at which the system is at higher duress due to full system scanning alongside the continuous On-Access Scanning.
