Well, this rises an interesting point for me: are there advices on
how to configure a particular system for best R performance with
large datasets? I've looked into the R system guide and could not find
anything (that document is a bit obscure for me, must recognize).
Do you get the 800 Mb by starting R with a particular option?

(BTW, I do not remember how much swap I defined for my linux
system, how could I check that?. Excuses for the not-R question)
