I am still experiencing dismal performance - local shapes are slow, very slow to draw, ArcGIS services are even slower, and adding a WMS service is even worse. The TOC control for URL Map services with many layers and groups is broken as well! Am I missing something? I have a robust laptop (Dell M3800 workstation class laptop with i7 processor and plenty of RAM and high speed fibre broadband), is there a graphics processor setting or something I missed? Any comments or advice? Anybody else experiencing this? I can't even demo this without it becoming embarrassing to esri...
