Salut

Testul lui imi pare cam teoretic. Nu ma intereseaza sa stiu cat ii ia unui
FS sa faca sync dupa anumite operatii (arata-mi un sens practic pt asta).
In schimb ma intereseaza daca am o structura de mii de directoare si sute
de fisiere in fiecare (rezulta milioane si zeci de milioane de fisiere in
total) cat de repede este accesul random la fisiere (pt un server de web
mare), sau daca servesc video ma intereseaza cat de repede citeste
dintr-un fisier mare (de ordinul GB) eventual citind din mai multe
asemenea fisiere in acelasi timp, sau daca fac un server de fisiere pt o
firma (in general documente intre 64k si 768k) rulez un dbench 100 (100 de
clienti simultan) si vad rezultatele etc...
