How quickly can MBSA scan one or more computers for security updates?
Although the first scan on a particular client will take a longer period o time than usual, subsequent scans will be much faster since the Microsoft Update and WUA configurations will already be established. On subsequent scans, performance depends upon the speed of the connection to the Microsoft Update site or Update Services server, as well as how recently the client has synchronized the catalog from its server. The number and types of products installed can also influence the performance of a scan. Be sure to check these timings based on your own hardware configuration and server settings since performance will vary. Note: Scanning for the various administrative vulnerabilities can add time to this process, particularly when performing the check for weak passwords.
