Did you use -j4 or -j2 last time?  Using too many simultaneous jobs

No, I still get my 6 to 7 min (with -j8 on Core i7).

Did you update your anti-virus software, perhaps?  Or any other
system-wide updates?  Look in the system logs (a.k.a. "Event Viewer"),
under "Application" and "System" for clues.
