I find Linux much more responsive than for example Windows 2000 which we
use at work. I can't do anything else if I am unzipping large files, or
performing any other heavy task at the same time. In Linux it's no
problem unzipping file at the same time I am playing a video etc.
What kernel are you using? 2.6 has the option CONFIG_PREEMPT which is said
to make the gui more responsive and should be enabled for desktop
systems. Also, you want to make sure you have DMA enabled on your hard
drives. Execute hdparm /dev/hdX on each hard drive and look for
using_dma. The same tool can be used to activate it. When DMA is
disabled, it can really affect the performance.
