I was using NetBSD 1.6 before, which was good and smooth. But when I 
switched to 2.0, I noticed that the mouse cursor tends to get much more 
jerky or even frozen in X under heavy load, sometimes with extremely 
long pauses. For example, when I unpacked pkgsrc.tgz in /usr, it was not 
jerky - it was completely, 100% frozen for 10-15 seconds. Which means 
that there was a 15 second pause when I couldn't move the mouse at all, 
the whole system didn't respond at all.

But even if the disc/CPU load is not so high, the mouse cursor very often 
gets jerky during normal, regular tasks - for example when a page is 
being loaded in a web browser, etc. 

Why is 2.0 so much worse in this respect than 1.6 was (Linux on the same 
PC is also much, much smoother)? Is there anything that can be done 
about it?

My system:
Intel Celeron 2.4 GHz
512 MB RAM
XFree86 with nv driver
