Hmm, yes. Time for a little tuning in /proc/sys/vm/*...

Here's my /proc/sys/vm/swapctl:
8 8 1 8 0 0 0 0 \
64 4 1024 1024 -200 1 1 0

Note the 1024 values for SWAPOUT_WEIGHT and BUFFOUT_WEIGHT,
this means that the system will be somewhat less agressive.

I even wrote documentation for these files :-)

how's performance with the uPatch I just posted?
