Which data are you referring to? Maybe I missed it as well? The only data I've seen so far that shows any effect of open-paren-in-column-0 is the one recently (as in "after your above messages") posted by Alan, and this data says nothing about slow or fast machines, shows a relatively small performance difference (not negligible, but within a factor 2), and considers a situation expected to be rather rare.
