Ok, things improve vastly and the system is usable again. I cannot
"notice" any difference with ac10 in terms of speed.

I attach the top and vmstat outputs while running updatedb (reads all
the files in the filesystems) and starting evolution for the first time
(touches all the mail folders, that's hundreths of files). It starts
smoothly in seconds.
