Yeah and last LSF/MM we concluded that it's not as a big disadvantage as we
previously thought https://lwn.net/Articles/931406/

How nice, thanks for that!

Do you have some refs to Mike's tests so that we could run them here too
with SNP guests to see how big - if any - the fragmentation has.

I ran several tests from mmtests suite.

The tests results are here:
