but it is still 10x faster than a previously owned shareware called synchromagic, that did use a slow checking method

in my version , which may not be the latest, pressing F6 brings up the comparison options & you can choose either file time and size,[ Identify equal files by comparing modification time and size.] [ or file content.
i think a new install defaults to the time and size method
I was referring to the compare by content option which Sirtel was using and given its nature, would obviously take a long time.

The immediate subsequent sync taking a shorter time is likely due to Windows RAM caching of recently read file system tables rather than any database that FreeFileSync keeps (if it had been a FreeFileSync database, then it should still be just as quick after 24 hours).

Yes, FreeFileSync defaults to file size/modification time and that default setting is very quick for updates as that just transfers changed files same as Dropbox does. The compare by content, however, is not.
