Huge pages are available in 2 MB or 1 GB sizes and can be a benefit to hardware as they create fewer entries in the adapter page table.

Onload applications should not use 1 GB huge pages otherwise every Onload stack would allocate 1 GB huge pages which might not even be required.

The OS huge page size should be set to 2 MB only. A mix of  2 MB and 1 GB sizes is not recommended.
