  Do I have to rebuild in x64 for a performance boost? Reply Contact we're currently running .Net 2.0 Apps on a x64 IIS7, with WoW enbled for the pool. However we're planning to migrate those Apps to 64 bit version. Then here comes a questiong, is it helpful for page performance if we really made the rebuild? this is a critical question for both system administrators and budget makers. hope to get your replies, since this really is a puzzling question. We've read a lot but hardly find any infomation clearly addressing this question.

  Re: Do I have to rebuild in x64 for a performance boost? Reply Contact Are you talking about memory paging or are you talking about performance of an web page? Memory Paging: If you have an application that is memory intensive resulting in heavy paging then yes you will see benefits of moving onto 64bit as your application will have pretty much infinite virtual memory to use and thus will not result in paging. Ofcourse all this is assuming that you will also have enough physical memory on the machine. Web page: It is difficult to answer without knowing what the page is doing. But if this is a simple .aspx page, which doesn't require lot of memory, than it will perform better on Wow64 than when run on native x64. Typically when run under Wow64 applications have a smaller memory footprint and they tend to be slightly faster. Overall it is prudent to port your 32-bit applications to 64-bit.
