That seems slow for that much horsepower, but computers vary a LOT based on how old they are, how many tasks are loading at start-up of the PC, coming out of sleep mode, etc.
Try using Sleep instead of Hibernate, if that's an issue.
You might also try running the software on another PC if you have access to one and see if it performs similarly.
If you don't use GPS, a big part of our start-up time is reading and sorting 70,000+ cities, so we might be able to trim that file back as a possible step.
