I have constant IO operations provided by copying ~250GB of data from/to external drive. Copying takes really lots of time and slows down the whole system noticably. 2. When any bigger application starts whole system slows down - i.e. my xorg/xfce4 keeps me waiting some seconds for action, still i can hear fluent mp3 stream behind. After application is loaded it works pretty fine until it starts operating on a data or unloads. When VBox starts the vmachine I get terrible glitches, then when everything is loaded system and vmachine works fine until it needs to load something that again slows down the whole system, then when I want to shut down the machine it gets unresponsive. 3. When the swap starts working things also gets really bad. I can work on VESA xorg driver, I can have no multimedia drivers, but the system performance is really important factor for me and working like this is really unpleasant on a pretty modern machine :-( I dont want to even think to switch to Ubuntu :-P Any hints on how to fix this situation are highly welcome :-) --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
