I have 40 machines (from Windows XP to 7, different configurations) in my company and I am responsible for maintaining them. What I would like to do is to measure the impact of new updates and new software installation on the performance of these PCs.
For this purpose, I need first to have a common metric for all the computers. I thought that such a metrics, could be time needed to start MS Outlook or MS Excel, because these two application are mostly used. Second, I need a way how to measure it. I thought about wrapping, e.g., ms outlook, to track (and send to a server) every k start how much time it needs to be ready to work with.
Does anybody have any experience with measurement of PC performance across the organization? Are there any commercial solutions for this purpose?
