that was my first attempt. Since the CPU usage/load average 
is already low, it had no effect at all.

tried dd with bs=default and still interactive processes 
(eg repainting a firefox screen, that would normally stay in 
memory when I changed to another screen), were slow 
(presumably the firefox screen had to be paged in from 
disk).

Thanks for the suggestions
