{"translation":"https://translate-dev.freebsd.org/api/translations/documentation/articlesvm-design_index/id/?format=json","source":["In regards to the memory overhead of a page table verses the `pv_entry` scheme: Linux uses \"permanent\" page tables that are not throw away, but does not need a `pv_entry` for each potentially mapped pte.  FreeBSD uses \"throw away\" page tables but adds in a `pv_entry` structure for each actually-mapped pte.  I think memory utilization winds up being about the same, giving FreeBSD an algorithmic advantage with its ability to throw away page tables at will with very low overhead."],"previous_source":"","target":[""],"id_hash":-1297362570668637025,"content_hash":-1297362570668637025,"location":"documentation/content/en/articles/vm-design/_index.adoc:369","context":"","note":"type: Plain text","flags":"","labels":[],"state":0,"fuzzy":false,"translated":false,"approved":false,"position":82,"has_suggestion":false,"has_comment":false,"has_failing_check":false,"num_words":80,"source_unit":"https://translate-dev.freebsd.org/api/units/615451/?format=json","priority":100,"id":1404379,"web_url":"https://translate-dev.freebsd.org/translate/documentation/articlesvm-design_index/id/?checksum=6dfed79d9e68849f","url":"https://translate-dev.freebsd.org/api/units/1404379/?format=json","explanation":"","extra_flags":"","pending":false,"timestamp":"2022-03-09T18:23:49.660019Z"}
