Sorry no, I have no idea why it would take longer. The exact behavior is this as follow:
[X] skip sublink parsing for contact forms
- Parse imported URL and scan for contact forms; stop if found - if no form was found, scan for sublinks and scan each site (sorted by score) for contact forms and stop once found
[-] skip sublink parsing for contact forms
- Parse imported URL for sublinks and scan each site (sorted by score) for contact forms and stop once found
That sublink parsing is still done if no contact form was found...so in the worst case it is indeed taking longer
