A group of 2 sch, a pld, and a blm, all around +43 arms/armor: 90-100 took about 24 minutes.
Another group of 2 drg a pld and a blm all around mid 90s, though the pld had a +87 weapon: About 24 minutes for completion, 90-100.
Both runs used 5 strength and 3 Rages.
Of course, this is just what I've seen on my own runs as pld, but I don't see any time difference.
