Not having done that, I can't speak from experience but it really is an individual decision. My first job was 6-1/2 years, the second, 9. I chose to stay because I liked what I was doing and the people I worked with, the work was nationally important (contracts with the intelligence community), I was very well paid compared to peers (according to surveys I read), and the benefits were top-notch. And, to be complete, I really hate interviewing and starting out at the ground floor in new jobs. Keep in mind, this is me. Your mileage may vary.
