I cannot say anything about the time… it heavily depends on the system (CPU, hard disk), number of files on your disk, type of files, etc.
If you want, you can turn on the creation of the report file in the program settings - and set the OK files to be included there as well. The resulting report will certainly be rather big, but you will see in detail what was scanned (e.g. if anything was scanned twice).
