iis ftp : slow transfer on network share
Hi
I have some problems by virtual directory with network shares. Situation1: We have on Server1 ftp installed. Server1 is a Windows Server 2000 SP4. On ftp Server 1 I created a new virtual directory with the name PRODUCT. The virtual directory (PRODUCT) is a network share on Server2 \\server2\ftpfolder. When i start now on a Client1 a ftp transfer from ftp://server1/product than is the traffic by 35KB/s average. Sitation2: When I install a FTP on Server2 and create a virtual directory name is also PRODUCT on the same folder C:\ftpfolder (not on a network share) than is the traffic nerly 10 times faster by 330KB/s average. I connect with ftp://server2/Product I used a tool to show the network connections Situation1: I saw that the connection between Client1 -> Server1 is a ftp connection Server1 -> Server2 its a netbios-ssn session. The client1 connect not direct to Server2. Does it possible that this way of communication on a WAN connection 10 times slower is? Thanks for help babagallo
Yes both server are in the same 2003 domain.
the authentification works with a domain useraccount for ftp transfer. Netbios transfer from server1 to 2 works with 22MB/s, because there in the same site and subnet. When I install a ftp server on server2 it works fine, than are the connection also by 350KB/s. In additional I disable mcafee Virus scan on both server. I think I will try to install a third part ftp Server and do a few tests. regards babagallo [quoted text, click to view] "Bernard Cheah [MVP]" <qbernard@hotmail.com.discuss> wrote in message news:erdOfKGOGHA.648@TK2MSFTNGP14.phx.gbl... > Well, you have done good analysis. > becaues server1 access server2 via UNC convention, hence netbios was used. > The part that I don't get it is that, it can't be that slow :) > how do you authenticate from server1 to 2? both in domain? or you just > send in server2 user credential ? > > if you use windows explore to copy big files from server2 to server1. how > long? what if you have direct ftp or web on the server2, how fast server1 > can retrieve or download those files? > > -- > Regards, > Bernard Cheah > http://www.iis-resources.com/ > http://www.iiswebcastseries.com/ > http://msmvps.com/blogs/bernard/ > > > "babagallo" <paperjam1@gmx.ch> wrote in message > news:%235VlP37NGHA.3788@TK2MSFTNGP09.phx.gbl... >> Hi >> >> I have some problems by virtual directory with network shares. >> Situation1: >> We have on Server1 ftp installed.

I did now exactly the same test with the tool G6FTP Server.
With this software I have 300KB/s average. I stop this server start IIS5 on the same computer with FTP and the transfer is by 38KB/s. After that I installed the FTP Service on a Windows2003 Server (IIS6). The Virtual directory connect to the UNC path \\server2\ftpfolder. I have also a speed of 35K/s on the Windows Server 2003. When I start parallel ftp transfer from Server1 than I have the transfer rate commulate. Example: 1 ftp transfer = ~35KB/s 2 ftp transfer = ~70KB/s 3 ftp trnasfer = ~105KB/s [quoted text, click to view] "babagallo" <paperjam1@gmx.ch> wrote in message news:uW4HmAIOGHA.3284@TK2MSFTNGP14.phx.gbl... > Yes both server are in the same 2003 domain. > the authentification works with a domain useraccount for ftp transfer. > Netbios transfer from server1 to 2 works with 22MB/s, because there in the > same site and subnet. > When I install a ftp server on server2 it works fine, than are the > connection also by 350KB/s. > > In additional I disable mcafee Virus scan on both server. > > I think I will try to install a third part ftp Server and do a few tests. > > regards > babagallo > > "Bernard Cheah [MVP]" <qbernard@hotmail.com.discuss> wrote in message > news:erdOfKGOGHA.648@TK2MSFTNGP14.phx.gbl... >> Well, you have done good analysis. >> becaues server1 access server2 via UNC convention, hence netbios was >> used.

Well, you have done good analysis.
becaues server1 access server2 via UNC convention, hence netbios was used. The part that I don't get it is that, it can't be that slow :) how do you authenticate from server1 to 2? both in domain? or you just send in server2 user credential ? if you use windows explore to copy big files from server2 to server1. how long? what if you have direct ftp or web on the server2, how fast server1 can retrieve or download those files? -- Regards, Bernard Cheah http://www.iis-resources.com/ http://www.iiswebcastseries.com/ http://msmvps.com/blogs/bernard/ [quoted text, click to view] "babagallo" <paperjam1@gmx.ch> wrote in message news:%235VlP37NGHA.3788@TK2MSFTNGP09.phx.gbl... > Hi > > I have some problems by virtual directory with network shares. > Situation1: > We have on Server1 ftp installed.

Mm.... so a remote UNC path request via ftp which is done via netbios
connection slow down the file serving in the requested ftp server. solution ??? none. let me ping around and see if we can do more test. -- Regards, Bernard Cheah http://www.iis-resources.com/ http://www.iiswebcastseries.com/ http://msmvps.com/blogs/bernard/ [quoted text, click to view] "babagallo" <paperjam1@gmx.ch> wrote in message news:%23Olbs4IOGHA.740@TK2MSFTNGP12.phx.gbl... >I did now exactly the same test with the tool G6FTP Server. > With this software I have 300KB/s average. > I stop this server start IIS5 on the same computer with FTP and the > transfer is by 38KB/s. > > After that I installed the FTP Service on a Windows2003 Server (IIS6). > The Virtual directory connect to the UNC path \\server2\ftpfolder.

I've seen the same behavior with a setup on a couple of my servers.
Server A is the FTP server which has some virtual directories mapped via netbios shares on Server B. Once an FTP user connects, if they download "local" files from Server A the speeds are fast, but if they download "remote" files stored on Server B the speeds are about 1/10 the speed. The network link between Server A and Server B is a dedicated 100Base full duplex link.
hjh
I can't find any information about this behavior ................ :(
