"If it's worth doing, it's worth doing to excess." Or maybe not. Try turning on -verbose:gc and see if you're going through a lot of garbage collections. If your max heap is 512mb and you're using 400mb of it for the cache, there may not be much left for request processing. Should also try a memory profiler to see just how full the heap really is. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
