Or more easily, by putting this in your web-browser:
ftp://visibull.frec.bull.fr/PGS_bgwriter/
I'm presuming these graphs are traffic to the disks, right? Do you have
a measurement of the requests from postgres? I'm not sure how you'd get
that but it'd probably help with understanding the graphs.
Maybe there's a way to get the kernel to be more aggressive with
pushing pages out to disk? It has a bgwriter too...
Have a nice day,
