The amount of time spent in a GC operation is dependent almost entirely on the number of live objects in the heap, not the amount of space being reclaimed. Having a smaller heap might improve your cache hit rate, but it will have little effect on the time used by GC. It is highly likely that your webapps have a memory leak. You need to use a profiler and find out what's eating up all that memory. If you set the heap size to a smaller value, you should be able to provoke the situation earlier, but it certainly won't fix it. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
