I've installed small amounts of RAM into machines and have them speed up more than an order of magnitude. The speedup was because it stopped swapping. Modern computers have other similar bottlenecks that can show massive improvements for what seem like small changes.


That's a bit of a knee point though.

If your machine doesn't have quite enough RAM, it will swap and likely be unusable.

Once you have just enough it will fly, and adding more RAM will make little difference.

I can't imagine the OP's aged stack is so low on RAM that he puts up with swapping.


As I said, there are lots of other knees. For example, a slightly increased L1, L2 or L3 cache size can have a similar effect.
