This might explain why I didn't see this behavior, because the external USB drive that I booted 3.2rc1 from was a USB3 drive that internally used RAID0, so it's probably faster than most. Might I ask whether your external USB drive was USB2 or USB3, whether it was an HDD or SSD, and whether it used RAID0?
