Can I just say that the engine used to scan drives/folders/files using the context menu option is horrendously slow?

For instance I chose my second drive (aka D as the target drive for a scan, combined data no bigger than about 40GB. I right click on D, choose scan with S&D, then take a holiday to Tahiti. Should be finished by the time I get back! :sarcasm:

Does this appear to be the norm? Are the developers working on a way to improve these times, or is this by design?
