I'm running this in a virtual machine without a ton of resources, and I haven't seen any other posts about this, so I'm wondering if the December CTP is handling resources differently such that my particular configuration comes out on the losing end.
It could be that it's having trouble connecting to the MSDN web service to resolve links to online content. If you're using the help file builder, set the SdkLinkType property to None to disable it. If you're using some other build script, edit your sandcastle.config file and modify the line in the ResolveReferenceLinksComponent to set the link type to None:
<targets files="C:\Program Files\Sandcastle\Data\Cpref_reflection\*.xml" type="None">
If the build time returns to normal after that, it was probably the cause. Sometimes the web service is slower than at other times but I haven't seen it that slow.
