Thanks, Joel My understanding of the performance issues there are that they are not related to what's in the cache, at least not after the first run, since we will preheat the cache for processes after we know what pages are typically in use. It's actually my understanding that the issue is one of having lots of static constructors which are not precomputed, combined by a large API surface that requires vtable linkage fixup on an API by API basis, which is also not precomputed (unless you ask fir it via prebinding).
