cheap cheap excuses but since f… 5 years you didnt added the core feature bandwidth limiting for insynchq itself.
5 YEARS GOD DAMNIT!
you even wrote that you rewrote the core for v3. well, IF you did that then wtf you didnt implement bandwidth control/limits too?! again, you had FIVE YEARS!!!
China builds a damn specialized hospital in under a week and you need 5 years AND COUNTING to provide a feature which is even provided by google themself, which you said you beat in features and performance. well, so far you didnt.
right now i have to QUIT INSYNC in order to get my upload bandwidth back so my family can watch tv etc etc. OR we , the paying customers, have to buy more software to fix the problems you did cause.
sorry, but the performance of your dev team and project owner for the last 5 years was more than poor.
