> When starting a download we receive calls to updatePrrogress and corresponding javascript callback this many times, so CPU will get to almost 100% and UI will non or very slowly responsive.
> I just made a workaround in https://github.com/OliverZiegler/cordova-plugin-file-transfer.git on branch iOS_throttle where the updateProgress event will only be send to the javascript source every second.
> We didn't get this issue on Android.
