Client side doesn't implement spatial index, so snapping manager has to scan all available geometries to find the proper point to snap to. For IE8, the javascript engine is quite slow compared to other browsers. When the number of features gets large, it will be an issue.

UP to recently all was fine in IE 8 for us, mainly because we use Google Chrome Frame to get IE to run everything in Chrome.  However we have a few PCs that don't have this installed.  For them, IE8 simply fails affter a few map operations.

It was fine until recently - anyone any hints on how to track down whatever it is I have added IE doesn't like?

PS - I found what was killing IE 8/9 - I'd added a snapping layer that was our fine detailed basemaps.  When zoomed in to a level these switched on AND in an urban area, IE just couldn't cope with that amount of vector data getting sent locally (I guess)

I rural areas, without so many features it could cope.
