Hmm. I've never had this problem before. I have the choice of 'Ondemand', 'Conservative', 'Performance' and 'Powersave', or 800MHz, 1.6GHz, 1.8GHz and 2GHz. Usually it's on 'Ondemand' (as I have a laptop). Even when it's at full speed, even the home directory takes 2-3 seconds to display the icons. Sandy On 23/12/11 12:51, Glenn Ramsey wrote:
I had/have this problem on a Kubuntu box (currently 10.04). It used to be pretty snappy on 8.04 with KDE 3.X, but after the upgrade to 10.04 was annoyingly slow. That was partly because of KDE 4.X, but mainly because of the default cpu throttling settings. The machine has an AMD 4800+ and the defaults for powernowd are lower load limit=20, upper limit=80. What it appears to do is linearly scale the CPU speed (from 1000-2500 MHz) between these limits based on load. I have set the limits to 10 and 20 so that if anyone is doing anything it goes at full speed and only throttles back if there is nothing at all happening.
Not sure if this will help you, but it's a possibility.
