From what I read about the DH it was sampling on each wheel at something like 100 times a second, so it is hard to believe that there's a 500 ms "lag time" in the system processing. If that were true, at 100 miles per hour, the car would have traveled over 600 feet between the time road imperfections were detected and the system reacting, which is a bit much to swallow.

Is there lag time? Probably. Is it 500ms? Highly unlikely.
If it's sampling at 100 times a second, then 500 msec does actually sound reasonable. It would probably take 10 or so samples before deciding whether to change and by how much, then it I'm sure it take some time to adjust the mechanicals to that setting.
