Makes me wonder how much performance Windows is leaving on the table with its primitive support for large pages. It does support them, but it doesn't coalesce pages transparently like Linux does, and explicitly allocating them requires special permissions and is very likely to fail due to fragmentation if the system has been running for a while. In practice it's scarcely used outside of server software which immediately grabs a big chunk of large pages at boot and holds onto them forever.
