Comment 151 for bug 125970

Indeed FF3 shows a scrolling performance regression for very large tables but it has nothing to do with THIS bug, as other posters already noted. Please look at bug #54542 which is a 'meta' bug for all large table perfomance issues. There are decent test cases in bug #54542 that would stress even modern machines. Perhaps you may open a new bug and make bug #54542 depend on it. I'm obsoleting the last unrelated testcase.
