I believe I've found the problem of excessive swapping with 1GB of memory.

There is a script "/usr/lib/pm-utils/power.d/laptop-mode" that is setting these weird values to VM tunable kernel parameters when on AC power:



The line 69 of the script is the following:

        write_values 0 10 5 500

Changing the line with these values resulted in being able to run the system with 1GB without swap and good performance.

        write_values 0 90 20 500

I think it needs some attention.
