[OpenLayers-Users] Firefox performance issues on Windows

[Matt Williamson]

Hi Alexandre,

Thanks, but I'm not referring to loading performance, but  
interactivity performance. I'm getting about 2 fps when dragging/ 
panning the map, while I get >15fps in other browsers on the same  
machine. Should have been more specific, perhaps.
