While domain controller performance may not be affected if the server doesn't have required resources, the Defender for Identity sensor may not operate as expected. For more information, see [Microsoft Defender for Identity prerequisites](prerequisites.md).

The sizing tool measures the capacity needed for domain controllers only. There is no need to run it against AD FS / AD CS servers, as the performance impact on AD FS / AD CS servers is extremely minimal to not existent.

For example, the following image shows a set of results where the **Maybe** indicates that the **Busy Packets/Second** value is significantly higher at that point than average. Note that the **Display DC Times as UTC/Local** is set to *Local DC Time*. This setting helps highlight the fact that the values were taken at around 3:30 AM.
