Maybe because you have 6gb of ram! I've got 4gb and can normally get a few hours if I'm not messing around with too many other programs at the same time
I have 8GB and an i7. Still doesn't help much with slow down. In a really busy game I get about 10 mins of proper work, in newer and simpler projects up to 30 mins of work.
Saying that, by visiting the rules in 2 really full actors one after then other and then using preview will pretty much slow it to an unusable speed in the space of about 3 minutes.

If doing a lot of switching actors I still get slow downs after 10-20 min.
thinking of getting 8G ram
But you did not say what program you were using? I'd really like to know.
