I have only 1GB of RAM and a 2GB swap. My scaling governor is set to
ondemand and I don't have a problem with audio (playing oggs on vlc)
skipping with disk IO and ftp happening simultaneously.
My kernel is 2.6.20-16-generic on Ubuntu 7.04.
Do the files work properly when they are the only thing running?
