Dobry den,
mam tak trochu problem s vyuzitim CPU pri kopirovani souboru po LANu
pres sambu a FTP. Pokud zacnu neco kopirovat, jede to od 2MB/s do 4MB/s, a
vyuziti cpu je 100%.
Kopirovani souboru na linuxu na stejnem disku jede cca 5-6MB/s, tzn. 5MB cte
a 5MB zapisuje. Pri kopirovani pomoci mc je vyuziti cpu take skoro 100%.
Nejak se mi nezda to vyuziti, prece ta masina neni az tak slaba.
DMA dle vseho jede, nejak mi dochazeji napady a diagnosticke nastroje. Jeste
jednu vec bych mel zminit, BIOS mi nedokazal tento disk nadetekovat, nicmene
linux si snim poradil a nasel ho.
Mohli byste mi prosim pomoci s odhalenim problemu. Je na vine obycejna eth.
karta? Zda se mi to ale nepravdepodobne. Prikladam nejake informace o
systemu. K routeru nemam az tak snadny fyzicky pristup.
Lehce se mi nezdal vypis dmesg, ale nevim co si ztoho mam presne odnest.
S pozdravem a diky,
Filip Jenicek
