Well, we were there at 8am and lined up back to the ticket sales, but only 4 rows. At 8:05ish, they opened 2 more tapstiles. At 8:15 they had us going into the park, but we had to stop right at the first stop light. At 8:30ish they moved us up to the Sunset Blvd cut off and told those people to head on over to RR if they wanted. Almost no one moved. By 8:50, we were moving and through the arch, where they let us fend for ourselves and start a line. We were done by 9:15, but it was a nerve-wracking wait until you got to the proper queue.
We did TS right after that and it was a 45 min wait... pretty accurate. What surprised me was after that, at 10ish, we headed to ST and that had a 45 min wait. The entire queue right around the trees was in use. We did that and it was lunch time, by then.
Anyway, definitely needed to be there early if you wanted to ride SDD without a 105-135 min wait.
