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). I'll be glad to post profiling results here, if of general interest. Previous profiling efforts point at file IO being the bottleneck. Too much of it is, apparently, done too slowly.
