Hi Frode,


I think I was able to duplicate the issue.

I will now transfer this issue to our developers to see if they can do the same in debug mode, and determine why this happens. You should get reply from them during the day.

Hey

Thanks for the very fast update :-)

MaxTransferRate works fine now with ftpSimplicit on slow speeds, like 10-800 KB's, but when you try to limit it for anything above 800 KB's it doesnt work. I can hardly see that any will limit the TransferRate to above 800 KB's but you never know

Frode,

I believe I have duplicated this issue. I will now forward it back to Grof for him to check what could be wrong. We will inform you as soon as we know more on the case.

Hi Frode,

The behavior you are experiencing is caused by activation of transfer rate control mechanism in the component when MaxTransferRate property is set. Because of extra buffering of data and transfer rate calculations it is normal that the actual speed of transfer is lower when expected speed is large.

I hope this information helps.

Hey

Thanks again for the quick reply. My Issue is the following. I limit the transferrate to 810 Kb's. transfering a 160 MB file the avrage transferRate is 3600 Kb's. If i limit the transferrate to 800, i get an avrate speed of 760 witch is perfetcly fine. Here's a example you can use to se the issue

Option Explicit
Private WithEvents ftp As wodFtpDLXComLib.wodFtpDLXCom
Private Sub Command1_Click()

ftp.Timeout = 40
ftp.HostName = yourserver
ftp.Protocol = FTPSimplicit
ftp.Port = 990
ftp.Login = user
ftp.Password = pass
ftp.Compression = 0
ftp.Blocking = False
ftp.Passive = True
ftp.MaxTransferRate = 829440 ' 810 KB's
ftp.Connect

End Sub

Private Sub ftp_Connected(ByVal ErrorCode As Long, ByVal ErrorText As String)
If ErrorCode = 0 Then
ftp.PutFile c: est.avi
End If
End Sub


Private Sub ftp_Progress(ByVal Position As Long, ByVal Total As Long)
Debug.Print Speed & ftp.TransferRate / 1024
End Sub

Frodo,


What is issues here? I don't understand it.

From your last reply I can see that all is working as expected. When you set MaxTransferRate to 800kb, file upload transfer is 760kb.

The issue is

Maxtransfer rate works up to 800 KB's

If you try to limit above 800 KB's you will see that it doenst limit the transferrate at all.

Plz use the test code to see for yourself

Hey

I got exactly the same result with Serv-U. I dont see this as an big bugg tho, can hardly see any of our customer limit the upload rate above 800 KB's. So thank you again for fixing the initial bugg report


Best Regards
