I'm not about to publish results, publicly, for particular vendors products - don't think it would be fair. What I would say, is that outside of using other products to reduce paging as much as possible, my recommendation (on balance) would be a good hardware RAID implementation for pagefile volumes (unless you are talking about monster size servers - ie not necessarily terminal server implementations). Uncannily enough, there was a debate, some time ago, here, regarding the usage of hardware RAID on terminal servers - at the time, some contributors behaved like it was an outrageous, unnecessary, and over-the-top, practice to use hardware RAID, on terminal server. * Neil I think the cost /benefit of RAID controllers and managing disk performance exceeds the cost/benefits of buying the fast CPU available. The latest and greatest CPU always has a substantial price premium. I have seen substantial DISK bottlenecks in 4 different customers in the last few months. All had very low CPU utilization and lots of free memory, and still had poor performance and scalability. Upgrading the DISK subsystems improved performance and scalability in every instance.
