Really depends on what you are scanning.
Scanning P25 control channels is very different from scanning the marine frequencies.
So my answer is fast until we know more about what you want to scan.
I'm certain that if you search for scan rate you will find some examples.
The actual scan rate will vary based on the amount of traffic on the freqs in your list.

Scanning rate are only stated while scanning conventional analog frequencies, as digital and trunked systems scanning rate depends of how fast the decode of the data can be done and how the timings are set by the user.
If you set one channel to 45Mhz, the next to 150Mhz, next one to 450MHz and the last to 800MHz, they will scan very slowly in a SDS100/200 scanner. Maybe as slow as 20ch/s. Use channels with frequencies close to each other and it will scan faster than 100ch/s.

So basically the same rule we have always had to use...put the frequencies in numerical order. Interesting.

Except Ubbe doesn't have one of these scanners and didn't cite a source.
Maybe he has one now, I don't know.
Really, use search, there are threads on this with real life numbers.

I am fairly certain that I have seen a post from UPMan in which he stated that if you mix the bands in a favorites list it will slow the
scan rate down. Examples would be 48.0 MHz with some 455.MHz and some 800.0 MHz in the same list would slow the scanner down
because it has to keep switching bands. If you keep "like kinds" together (i.e. - all in the same band) it will scan faster.

Yes, but with a much bigger difference in speed than "normal" scanners. It was Upman who mentioned it here on RR that it is more important to sort frequencies with a SDS scanner.

Using the 'Auto' filter setting with conventional frequencies slows the scan rate down for sure. I think I'm going to change the way I set up my Favorites lists - put all the channels that need 'Invert' in one department, maybe sort that by frequency, then have another department with 'Normal' filter applied, etc, etc.

"Auto" slows down some but not all conventional departments for me. For Phoenix Fire VHF, it slows it to a CRAWL. When using auto on Arizona DPS UHF frequencies, there is no impact. Still scratching my head on that one. The only difference I can think of is that the VHF stuff has DCS's and CTCSS, while the UHF stuff is all CTCSS. I am suspecting that "auto" and DCS don't get along well, but I have not tested to verify yet.
