    Can one set 1280 2MB and allow 1GB RAM huge pages? There's a bash script that does on GNU/Linux (by the xmr-stak-rx programmer) but this expects
    Linux kernel software/settings not present on *BSD...

    FreeBSD's virtual memory system automatically merges smaller pages
    into larger pages if appropriate. This is done automatically and you
    don't have to change any settings. You can find a counter of how many promotions have happened in the vm.pmap.pde.promotions sysctl.

    Great... however, I installed ports/net-p2p/xmrig which says 1GB huge-
    pages are unavailable... is it inaccurate or I should bug-report to xmrig computer/software programmer/developer it's not programmed right for
    FreeBSD UNIX?

    As far as I know, FreeBSD's max page size is 2 MB. I think 1 GB pages
    are a Linux specific thing.

    I read they might still exist as 'superpages'?

    AFAIK, super pages are the 2 MB pages and they are the largest
    continuous allocations FreeBSD makes.
