filsystemets blockstørrelse, så vidt jeg kan lure.

Det kommer an på filsystemet, Reiser4 kan fx håndtere små filer effektivt.


Lidt ligesom, det normalt ikke giver den store mening i at implementere
ting i bits i C, da det alligevel vil fylde en byte i hukommelsen da,
det er mindste adresserbare størrelse. .. (giver kun mening, hvis man
har mange bits og kan pakke dem).

Ja, men du har vel netop mange små filer, for eller ville de blive cachet.
