Use a QTimer to count the interval between two
QNetworkReply::readyRead()signals then takeQNetworkReply::bytesAvailable()divide by 8 times (1 byte=8bits) the timer value (in seconds) and then adjust for the magnitude ( divide by 1024 for kb, by 1048576 for Mbps or 1073741824 for Gbps) -

as 1 byte is 8 bits it should be 8times
QNetworkReply::bytesAvailable()divided by the timver value to get bits/second iirc :)
4/4
