Currently, I’m only testing on one machine at a time. And I’ve tested on several machines of the same model with the same results.

There’s around 100GB of free space (SATA disk) on the server for storage.

I’ve recently upgraded my Windows 7 32-bit machines to 64-bit and have been experiencing slowness with deploys and uploads using FOG 0.32. I’ve observed that my Win7 64-bit image (~31GB) deploys via unicast normally at around 2.5-3.0 GB/min to an HP desktop with a 160GB Seagate hard drive until it reaches ~60%. From there the speed drops to under 1 GB/min and takes an additional 35 mins to complete. This is the same behavior for uploads and multicasts.

I’ve tried different Win7 64-bit images, other desktops of the same model and hard drive, and different networking gear which results in the same issue. However, pushing out a Win7 32-bit (~21GB) image to the same machine takes only 6 minutes with no issues.

I tried replacing the current hard drive (Seagate SATA/300 7200RPM 160GB) with a larger 250GB hard drive (SATA/300 7200RPM) and the deploy performed without any slow downs or issues.

I’m trying to find a solution without having to replace all my 160GB hard drives and I don’t quite understand why the 32-bit image works while the 64-bit image has issues when deploying to the same machine. Are there known issues with FOG performance and hard drive models? Or with Windows 7 64-bit vs 32-bit images and FOG and/or hard drives?
