howdy, y'all ---
so, i was looking over the offerings of the on_line retailing "usual suspects",
when i got to thinking:
q: to what extent does freebsd cache recently_used hard_drive files ?
q: under freebsd, to what extent are
hard_drive internal_caches and their sizes [ e. g., 2mb, 8mb, 16mb ]
important ?
i am not so much looking for a history_ and theory_of_operation as
i am looking for a "yes/no" to the question:
q: should i pay up for hd_cache, if the other hd parameters are the same ?
something else that i just thought up while typing this:
q: are hd internal_caches non_volatile ?
id est,
q: do the cache contents survive a power_cycle ?
[ some supplementary "fyi"s:
yes, i am aware that
hd access_times are a relative "eternity" to a chip_set's hd_port.
i am not thinking about ram_size and swap_size and "thrashing";
all of my boxen have plenty of ram.
i know i have to read it in the first time.
rather, i am thinking about opening and reading
some file that i recently wrote and closed.
]
in advance, i thank you.
please cc.

ps --- remember, slavery sucks; so, have a happy pesach.
