Was curious if anyone had any real world experience/observations regarding how Citrix performance was affected/increased by using either dual core processors or the new 64bit version of Citrix? We're looking to get some new hardware and are trying to sum up the general performance increases based on the following progression regular dual processor box --> dual processor/dual core box --> dual 64bit processors. Assume same amount of memory/otherwise identical hardware spec in each box. Any thoughts would be much appreciated. Also regarding the 64bit version of Citrix.if folks have had any negative experiences with it (red flags) or any other general feedback. Thanks! Chris
