Currently it takes me approximately 17 minutes to boot my computer. It takes another 5-10 for it to become useable. (I can make a pot of coffee before I can check my email). And this happens every morning.
My computer at home is usable in less than a minute.
I fully understand certain software must be loaded during boot to protect the computer/virus checkers etc etc, but the boot process can be optimized so these load more efficiently, allowing me to be productive quicker.
Based on my experience (which will vary per computer) I figure about $3-7k per year per employee is wasted due to slow bootup. Multiply this by all the employees in the government and it becomes a large number.
