Im trying to get the upload speed from my client to server.
try
                        {
                            Stream strm = ftp.GetRequestStream();
                            content = fs.Read(buff, 0, bufflength);
                            
                            while (content != 0)
                            {
                                strm.Write(buff, 0, content);
                                transfered += content;
                                progressBar1.Value = transfered;
                                
                                content = fs.Read(buff, 0, bufflength);
                                
                            }
                            strm.Close();
                            fs.Close();

Just put timing code something like below: (Note that I am only timing the FTP stream writing  so the TotalTime will be less than the real time (EndTime-StartTime).  This is just the speed of the FTP transfer)

If you want time want to give the users real time transfer estimates then you will have to create an event and do the same computations for each strm.Write()

try
{
    Stream strm = ftp.GetRequestStream();
    content = fs.Read(buff, 0, bufflength);
    DateTime startTime=DateTime.Now
    DateTime intervalStart, intervalEnd;
    TimeSpan TotalTime=TimeSpan.Zero;
    while (content != 0)
    {
	IntervalStart=DateTime.Now;
        strm.Write(buff, 0, content);
        IntervalEnd=DateTime.Now
 
	//Do something like this if you want to provide user with real time tranfer rates
	//RaiseTransferSpeedEvent(IntervalEnd.Subtract(IntervalStart));
	TotalTime.Add(IntervalEnd.Subtract(IntervalStart));
        transfered += content;
        progressBar1.Value = transfered;
        
        content = fs.Read(buff, 0, bufflength);
        
    }
    DateTime FinishTime = DateTime.Now
    strm.Close();
    fs.Close();
	
    long TotalSize=transfered;
    long TransferRate = TotalSize/TotalTime.TotalSeconds;  //Transfer rate in bytes per second
    TransferRate = TransferRate * 8                        //Transfer rate in bits per second
    float TransferMB = TransferRate / (1000000.0)          //Transfer rate in MegaBits per second (baud)
}
