WinPE 4.0 Slow LAN Transfer Speeds
Posted 02 May 2013 - 02:21 AM
First of all let me thank you for your excellent forum! I have learned so much from you all Unfortunately I have an issue which I cannot seem to find the answer too and was wondering if you would be kind enough to help me with it.
The problem as the title suggest relates to deployment speeds in using WinPE 4.0 (x64).
We currently have a bespoke deployment system that uses WinPE 3.0(x32), but this needs to be updated to WinPE 4.0 (x64) to allow Windows 8 deployment (Our deployment method uses OEM installation scripts which will only run in WinPE 4.0 (x64)).
The problem is the deployment time is roughly doubled since the upgrade! Both OEM scripts and Ghost64 (V12) take much longer to image the client. At first we thought it was a LAN driver issue, but this was eliminated by using 3 different driver versions and then later a USB->LAN converter, which again was significantly slower. Further investigation revealed the network traffic was dropping out completely rather than running at a constant slower speed. When data was being transferred the speed was comparable to WinPE 3.0, but the problem is the data isn’t being moved all the time. For example, the data will transfer for about 60 seconds and then stop for 30. Robocopy also displays the same characteristic (We transferred 50gb in WinPE 3.0 and the same in 4.0 with the results showing data being intermittently transferred)
All our clients are based on Intel chief river platforms.
The server is a glorified i7 desktop, 8GB RAM, Server 2012. It also has an LSI 9260-4i RAID card and Intel quad ET LAN card (teamed). Both have the latest drivers and the RAID card has the latest firmware.
If you need any further information please do not hesitate in asking.
Any help will be appreciated.

You can boot from HDD or USB using Boot Manager Menu and Microsoft Virtual driver
Or boot from RAMDISK using Grub4dos Menu and FiraDisk or WinVBlock driver.
Portable and Mini 8 have the full registry of Installed Windows 8
which is in any case much better than WinPE 4.0

- File servers (that store the images) data arrays are on RAID10.
- Servers use NIC teaming
- Servers are Intel server board with dual CPU (8 core)
- Servers have at least 24GB RAM
- Servers WDS set to not add PCs to AD
- All switches use link aggregation

We have made some progress..... Robocopy is now transferring files at the same speed in both enviornments.
Updating the Server LAN drivers and teaming software appears to have fixed this, but ghost is still slow.
This may be the version we are using because we have experience of differing speeds between ghost versions in the past.
I will obtain the V11.5.1 Ghost64 (the same version as our 32bit system) and post the results.
Edit: I think the LAN driver was the same version, but re-configuring the teams fixed the issue.
