Since you're booting from a DVD, the 5 minutes boot time seems reasonable. When you boot from this kind of support/device, a lot of things are loaded in the RAM itself. It also depends on the max speed provided by your disk reader.
Are you suggesting I boot from the ISO itself on disk? If so, I don't know how to do that.

I'm pretty sure it isn't doable...
