All the tests were done after a fresh reboot and they were ran
3 times in a row. Only the data from the first run have
been plotted in the graphics, but the complete data are available in

We have very nice results here (getting close to 50% of the time in
vanilla), but the overhead for small allocations is very high
yet. That will be addressed by adaptivity real soon, since we will not
have a compressed cache when it's not needed (like in 30MiB
allocation). In small allocations, it's possible to allocate all the
needed memory without swapping out, so vanilla kernel can perform the
allocation very quickly.
