Back in the "good old days" of Desqview I vaguely remember being able to set the "time slices".... or was it "clock ticks".... It has been so long I don't remember the correct term.
I bring this up because for quite some time now I've noticed downloads or streaming video, whatever, slow down if I do something else in another window. For example, I can be downloading a file in a browser and then open a game in KPatience and watch the download slow down and then speed up when I go back to the browser. Ditto when watching streaming video and playing a card game during the commercials.
This is more apparent in Xfce than in KDE, but it happens in both.
Is there anyway to set the time slices in either desktop?
