File Transfer Speed Problems

Joined
Apr 16, 2012
My server is Windows Server 2008 R2, and my clients are all Windows 7 x64

I can transfer files between clients and the transfer speed is around 65MB/sec, but transferring files to the server it slows to a crawl of around 3-6MB/sec. Also server becomes inaccessible to other clients while that painfully slow file copy is in progress.

On another possible related note. If i right click in one of the folders on a network drive and click new folder, nothing happens, but if i try it again it says "New Folder" already exists. Refreshing doesn't seem to show new files for a long time.

Also If I open excel or word for that matter and attempt to save a file on the network drive, it fails, but if i save it on my desktop and then drag and drop it onto the folder it allows me to do it.

client-server connection speed as reported by iperf is:
------------------------------------------------------------
Client connecting to server, TCP port 5001
TCP window size: 64.0 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.2.62 port 5140 connected with 192.168.2.1 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 491 MBytes 412 Mbits/sec

So it seems as if it's specifically a file sharing issue. There is no virus protection on the server, the client has Microsoft Security Essentials

Depends if you need it :) it's a role to transfer and sync between servers.


For now try to add these keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters



Value =DisableTaskOffload
Type = DWORD
Data = 1



Value =EnableTCPChimney
Type = DWORD
Data = 0



Value =EnableTCPA
Type = DWORD
Data = 0



Value =EnableRSS
Type = DWORD
Data = 0



Once done reboot your server
