As Darius stated, this part of the discussion is probably completely irrelevant to any performance issues you have. Regardless, doubling the heap size will likely _increase_ the cache misses, since you now have a larger target space being accessed through a fixed size cache space. This level of refinement is a real juggling act; unless your cores are staying very busy, it's unlikely to have any measurable effect. You need to collect more data so you can start ruling out causes, and GC information is probably the easiest to start with. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
