Let us know. Rumor has it that the first generation Intel dual-cores are nothing to write home about. Between Intel rushing to market, limitations of the chipsets and the NetBurst architecture I'm surprised it works at all.

One interesting report from Citrix was that an AMD dual core is faster than two separate cores of the same speed. They reported getting 8-10% more users on Citrix servers. It's a memory bus thing. I am thinking it might not apply to the Intel dual cores - but have not confirmed any of this. tim _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Chris Grecsek Sent: Wednesday, November 16, 2005 11:22 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Server Hardware - Dual core/64bit 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
