slow transfer on network share

[babagallo]

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

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?

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.

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

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.

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.
