I like this question cause mine is my house, I do have cable and my max up is 900, down is like 8000-10000
I found some calculation in steam forum here
http://www.steampowered.com/forums/s...5&pagenumber=1
and got this,
sv_maxupdaterate 24(used to be 12)
sv_maxrate 4267
sv_minrate 0
I do get a little laggy at times, but I have a 24 person server and 20 levels of heros, also 92 plugins running
If you have better advice jtp, I would like to hear it as well, always looking to be more stable
