Huge pages is good when a single process is reserving a giant block of memory which I think isnt that common.

You might have transparent huge pages on by default depending on the distro

No idea about hugepages but mmaping giant blocks of memory is extremely common. IIRC Chrome maps something like 1 TB on startup.

I think (?) you don't actually see benefit from hugepages unless you actually write to a large amount of memory though.
