One more, thing, the mac uses compression to avoid swapping-- CPU cycles are cheap, IO cycles are expensive.
see this ars technica article for an explanation-- yellow might actually mean--"compressing" and red might actually mean "swapping," though In any event, using 7.99 GB out of 8.0 GB (my situation), is perfectly normal.
Oh No, I'm using 9.5 MB of swap! Whatever shall I do?
