Dear SPMers, I'm using a Precision Worstation 3.6GHz and 3.0 GB of RAM (DDR). The Hard Drive is 140GB with 10GB remaining. Hyper-Threading is on. The system is Microsoft Windows XP. When I run an estimation, I run into a very noticeable problem, specifically on the second part of the analysis. The Processor/CPU usage hangs at 50% and does not want to use anymore processor. I've run the exact same analysis on a different and less powerful machine, and the second stage not only shows quicker processing, but the CPU usage works 90%-100%. What can I do to get my machine to work closer to 90-100% on the analysis? Thanks, Regards, Simona Brambati
