I see the hardware is of course an important aspect.

You could also try fread from #rdatatable and see if this works better for you.

Since I have quite powerful laptop, I rarely come to the limits. But this was different in the past. I did my doctoral thesis (R package development included) in part on an #EeePC. That was fun.
