My setup is the following : - kernel 2.6.1-rc1-mm1 + w29p2 - X either reniced to -10 or 0 (doesnt make a difference) - window maker - opera open on a fairly simple page (marc.theaimsgroup.com) in VS 1 - 2 xterms on VS2 - 4 xterms in VS3, one of which runs make -j 3 bzImage, another one 'top'. -> going from VS3 to VS2 then VS1 takes up to 5 or 6 seconds redrawing parts of windows on each screen. I also noticed that make -j 8 dep blocked the xterm it was run in for about a third of a second about twice a second. It does not seem to slow the process however since it takes the same amount of time as make -j 8 dep >/dev/null.
