OT:
Przy okazji pierwszego postu chciałbym się przywitać. Czytuję już forum od pewnego czasu, ale do tej chwili
pozostawałem tylko obserwatorem

Na Gentoo siedzę dopiero od paru miesięcy wcześniej było PLD - jak
na razie jestem pod wielkim wrażeniem całego systemu i środowiska, które się nim zajmuje. Wszystko tu
działa - żadnych problemów, żadnych konfliktów a już 4 stacje robocze i 3 serwery na to przerzuciłem.
Nie wyobrażam sobie lepiej zorganizowanego i sprawniejszego distro. Po prostu zachwycające

Pozdrawiam!

Czym to może by spowodowane?

Po jego kupnie jak sprawdzałem to jego wydajność wynosiła ok ~90MB/s.
