Hello list, I am observing an odd set of circumstances. I have a map that displays 8 fairly complex polygons. This map is extremely slow in Firefox on Windows on some of the systems in my office. Extremely slow = ~2fps or less when dragging/panning, for example, and CPU usage is through the roof on one core. The odd bit is, this same page is perfectly usable in Firefox (and Safari) on Mac OS X, and in Firefox on Linux. AND, it is also usable on the same version of Firefox (3.0.5) on other Windows PCs.
The slow systems are not old systems, either! They're 2.2 GHz Core 2 Duo systems with 2 GB of RAM. Comparatively, running the same thing on a 2.0 GHz Pentium M laptop is perfectly fine (e.g. ~15fps)! The only thing I can think that might make a difference is that the problem PCs have Via Chrome 9 video hardware (don't ask me, I didn't build them), whilst the aforementioned laptop has a Radeon Mobility X300--but still, not a high-end graphics card. Does Firefox use hardware acceleration for SVG rendering or something, and I'm suffering because of the graphics card? What other factors could account for this difference? By all reckoning, those PCs should be able to handle something like this with ease, but it totally chokes them up. (Incidentally, I checked in about:config and SVG is enabled-- disabling it made it 100 times slower yet!) The page in question is an intranet page (yes, I have the appropriate enterprise license keys), so I can't link to it...but it probably wouldn't help because this seems to be a problem specific to a subset of hardware or software. Also interesting, this may not be Google Maps specific--I've noticed the same performance problems while using vector graphics in OpenLayers on these systems. But I figured if anyone else knows what the problem is they'd probably be here. Anyone seen something similar to this, or know what might account for this performance bottleneck?
