Morphic slowness (was Re: Does *anyone* use MVC?)Bruce Cohen brucecohen at qwest.netFri Aug 2 03:43:28 UTC 2002
Tim, I tried this in my normal work image (3.2 gamma with all current updates, OS X VM 3.2.6Beta8) and got the attached results. It's been awhile since I tried to interpret a profile like this, but it looks reasonable to me. As far as I can see, a little less than half the time is being spent drawing the menu buttons and so on, and I think some of the rest is going to redraw surrounding parts of the browser and world background because the damage area may be specified larger than it really is (that last is a guess, though). Do you get anything seriously different?
