I tested page remapping time - i.e. time to replace a page in two
different mappings - the same should be performed in host and guest
kernels if such design is going to be used for communication.
I can only explain after-reboot slow copy with empty caches - arbitrary
kernel pages were copied into buffer (not the same data as in posted
code).
