From: Christopher Schultz [mailto:ch...@christopherschultz.net] Subject: Re: [OT] Followup on 32-bit versus 64-bit performance discussion(s)
So, back to the original question: will a 32-bit JVM on a 64-bit OS give me a bigger heap potential than a 32-bit JVM on a 32-bit OS? Depends entirely on the how the OS chooses to handle the 32-bit process virtual space. If the OS continues to maintain the 2 or 3 GiB boundary, your maximum heap isn't going to improve. If the OS allows all 4 GiB to be used by the process, then the heap could be larger. I haven't experimented to find out. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
