gentoo listelerinde gordugum basit bi komutu " time dd
if=/dev/zero of=/dev/null bs=1024 count=100000000 "
isyerimdeki debian(testing) makinede denedim.sonra ayni
makinedeki mandrake 10.0 da denedim sonuclar kafa
karistirdi.bunun uzerine laptop olan makinede ve server
olarak kullandigim ibm de denedim. Debian haric hepsi
birbirine yakindi makine konfigurasyonlari ve test
sonuclari asagida debian da niye bu kadar farkli.bir
performans problemi mi acaba karar veremedim.
