Description
We should enable the use of transparent huge pages on Linux by default. The solution is to set the UseLargePages flag to true by default, but try only using UseHugeTLBFS by default if UseLargePages is not specified on the command line. We would try both UseSHM and UseHugeTLBFS methods if UseLargePages is explicitly set.
