good question I was interested in learning about this too because I just got this server called NetFrame and to tell you the truth I never had any experance in running a real server before you know. A good freind of mine who works at my works help desk told me if it was a 100/10 it runs like this one at 100 and the rest at 10. I dont know how true that is. if you find out any different let me know. thanks
