If you have 128kb/s upload then you will only be able to serve about 3 MAYBE 4 people.. 128kb/s is only about 19Kb/s speed...Not 35Kb/s... A good rule of thumb to follow when converting in your head without using the 8bits per byte formula, is to just say that if you have 128kb/s divide by 10.. Safely giving you 13Kb/s to effectively use..
