My configuration is dual PIII 933 Mhz with 512 MB RAM, 1GB swap. Three
simulatenous compilations (gcc, kernel, gdb...each with make -j3), playing
XMMS and browsing web using Mozilla (3 windows) + XEmacs. Switching between
workspaces is slow...Everytime a page is loaded in Mozilla, XMMS stops for
a second before continuing. Mouse pointer jumps.

I have attached vmstat and top output from 2 different runs (with the same
load). Seems that swapping is not smooth. It suddenly jumps from 2896 to
26780. I have noticed similar behaviour with 2.4.10-ac10 (before applying
this patch). swpd entry doesn't seem to increase at all, even when the
machine has similar loads as the current load.

HTH.
