> In Google’s data centers, this improvement reduced TLB stalls by 6% and memory fragmentation by 26%.

Yet after Ctr+F-ing the paper for the term, I have yet to find an accurate definition of "fragmentation". Keeping in mind that fragmentation is an allocator's major enemy, it bugs me to realize that there is no universally agreed-upon formulation yet.

Does anyone more knowledgeable have a more informed opinion on the matter?
