So don't do that.  RHEL6 kernels are pretty ancient at this point,
and are known to have performance issues with huge pages.  If you can
replicate the problem on a modern kernel, somebody might be motivated
to look into it; but not on that platform.  In any case it's very
unlikely that this is a Postgres problem rather than a kernel problem.
