It seems to me also that KDE starts up faster on DragonFly than on
Linux, on the same laptop. But it's just a subjective impression.
However, anything involving heavy disk-writing activity -- untarring a
large tarball, for example -- slows down DragonFly a lot. (I think
this happened with FreeBSD 4 too, but my subjective impression is it's
worse with DragonFly, even though I ran FreeBSD 4 on an older and much
slower laptop.) Basically, when doing a lot of disk writing, audio
playback skips a lot, sometimes the mouse pointer or keyboard typing
lock up briefly, or clicking on an icon (even something simple and
quick like an xterm) has a very delayed effect, and so on. Linux
seems to behave much more smoothly. I never get audio skips unless
some runaway program is eating memory and the system is swapping a
lot. It may be due to the preemptible kernel, but that should then
slow down an untarring process, and I don't notice a remarkable
slowdown there either.
