(There are limits to this, but swapping can drag down performance in a hurry.) 2) Extra memory provides headroom for new services added to existing devices. 3) Extra memory provides headroom for unexpected increases in the memory requirements for existing services (sudden transient spike in the number of received routes, sudden route churn, etc.). 4) New SW releases will almost always require more memory. The amount of memory seems to grow at an exponential, rather than linear rate, although the rate certainly varies by OS (JUNOS would be closer to linear than Windows, for example). For all these reasons, I generally prefer to install double, triple, or quadruple the amount of memory I think I need today. (And, I try to do this for everything: laptops, routers, firewalls, etc.) In some cases, that has come in very handy. In others, it probably came in handy and I didn't even notice. And, that's kind of the point, isn't it? :-) Memory is cheap insurance.
