Hi Mike, How did you determine that the scans took 1 to 1.5 minutes per host?
What did the Security Center report as the time it took for your total scan time? This scan time considers the total number of IP addresses and not the actual hosts that were scanned. In other words, if Nessus is spending time trying to ping hosts that aren't there, this will cause your scan to take a bit longer. You could also extract the .nessus file from your SC3 scan and try this in the Nessus Client to see if there is any difference.
