Hi All, 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.
