File Transfer Speeds Server 2008 - Server 2003 1

[soulestream]

We have installed our first 2008 server. Currently it is only running as an archive server for old files. I have been running copy jobs across our WAN from other 2003 servers.

A 2003-2003 server copy runs around 300-400k/s.
A 2003-2008 server copy runs around 30-40k/s.

After reading several forum posts, I can't find an answer I am comfortable with.

Disable SMB2 seems rather extreme, being as we will be adding more 2008 servers.

Some have suggested changing the registry keys...

Change the following registry keys to 0 from 1:
HKLM\System\CurrentControlSet\Services\Lanmanserver\parameters\EnableSecuritySignature
HKLM\System\CurrentControlSet\Services\Lanmanserver\parameters\RequireSecuritySignature

Does anyone have a proper way to fix this issue??

Thanks

Soule

Sounds more like a switchport/duplex issue to me, 2008 is heaps faster then 2003 anything to anything

Do you have Service Pack 2 installed on the 2008 machine?

I would look at the speed and duplex setting on the server and switch if I were you.

We have a mix of 2003 and 2008 and don't see any real difference between the two as far as file copying goes.

Aside from duplex/speed setting issues...

1)Disable SMB signing, if your internal network security permits (if your not worried by internal hackers).

2) I only needed to disable SMB 2.0 for older versions of Office with an issue of extremely slow open/saves on a Terminal server.

3)Turn off Flow control at the switch, if your wiring is certified. If your wiring is not up to par, you may need flow control;if you really need flow control, you really need to correct poor wiring issues (that is, on a relatively small network).

We seem to have a similar issue.

10-12 mins approx from a 2003 to a 2003 box. Yet it's 90 minutes from the same source to a Win2k8 box!!!!

Even worse the 2003 destination box has a 1gig pipe yet 2008 has a 2gig pipe!!!!

Currently SP1, I will look into SP2 (although I thought it was just a security roll-up)

The switch/server is set to Auto is is running 2Gb (bound)/Full Duplex.

Disabling Flow Control may be an option, I will look at the switch to see if it is enabled. (with 802.3 I think it will be)

I found some references to users having issues with Broadcomm cards. I might try dropping an Intel in for good measure.

Sorry to jump into your thread soulestream!

FYI I've just thrown SP2 onto the box and I'll give it another test later.

We're also using Broadcom NIC's and have a similar setup - however we're using ProCurve switches without any flow control or anything. Just the using Teaming on BASP for the 2Gig pipe.

Cheers,



Steve.

Guys, I just ran into this and might of interest to you all;

File copying from down-level systems to Windows Vista or Windows Server 2008 is significantly slower if Intel I/OAT is enabled

One other thing you may want to consider doing is disabling the "Large Send Offload (IPv4)" setting on the NIC, this does cause issues and MS are aware of it.
