I'm using Openlayers, Geoserver and noticed that IE is very very slow to display WFS layers. I haven't so many WFS features, about 300. Google base layer appears after 1 sec. but my two WFS layers need each from 10 to 20 seconds to display. With Chrome, it requires only 2 seconds.
I tried to disable style rules, events, no change. It's really a client issue, my cpu goes up to 50% for iexplore during features loading. I tried with IE8 and 9, with two differents pc, same results.
It seems that I'm not the only one. I can keep using Chrome but would be interested to share ideas
