Large pages can be used on Windows without elevated privleges.

[Infini-PLEX]

Enabling large page support on windows only requires the "Lock pages in memory" user right, which can be granted on a per user basis in the Local Security Policy settings.

See the java docs (It says only Windows Server 2003, but I can confirm that it does work on modern Windows Server, not sure about desktop):

Can confirm this works on Windows 10 Pro. Just add your username to the Lock pages in memory policy. No need for admin privileges.

Before the change I'd see an error that JVM cannot use large page memory because it does not have enough privilege to lock pages in memory.

I also found this a couple weeks ago, it's in my fork.
