I know this has been explained very well in general, but I want to ask for advice on this particular situation. I hope it's not considered a duplicate.
I'm gonna install Lubuntu 16.04 (Or whatever flavor will perform the best.)
My friend will use it for mainly web browsing, movie watching and word processing.
We want the system to be as snappy as possible, given the old hardware.
What will perform better, 64-bit or 32-bit? Is Lubuntu indeed the best flavor?
By the way, my friend can't afford to upgrade the RAM. He is very poor with a near zero income. He's from a third world country. 20$ is like two weeks' salary for him.
