I have a 2.0 GHz P4 with an i845 Brookdale G chipset. Reading seems to indicate that the G means this is the scaled down el-crappo version of a chipset that ain't that great to start with. Considering my motherboard only has two slots, and is crawling with other quality features, that's not surprising. (Of course, every Dell or Gateway computer I've worked on recently has had the same thing in it, so these are common as dirt.) > Assuming you did follow the same test procedure (empty composition, create > 1 seg, move it across), getRectanglesIn() and computeSegmentRect() are You did say to "move it across the composition back and forth a couple of times" which I interpreted to mean "drag it from 1 to 100 and back, then repeat. That's what I did. From 1 to 100, stop, 100 to 1, stop 1 to 100, stop, 100 to 1. That could explain why I'm four times slower if you didn't do that much dragging. > Anyway, this demonstrates that contrary to what I thought, some kind of > caching scheme for the segment->rectangle computation might help.
