"Don't support IE".

Hi everyone, thanks for the answers, but I still confuse the things below:
(1)Should I use a server-side solution(wms) or browser-side(markers, vector)? I have no idea.
server-side: how to implement dynamic changes?
browser-side: performance in IE is not acceptable, and most of the user in my application will use IE.
(2)If use browser-side solution, does the cluster strategy only apply to the vector layer? But vector layer is more slow than markers layer.
