Memory use seems like a really pointless thing for users to care about. There's a widespread intuition that using RAM is inherently bad and low memory usage is a worthwhile goal, but it doesn't really make sense. The key performance goal is minimising latency, which is best served by using as much RAM as possible without having to swap out. RAM is now fantastically cheap. 16GB of DDR3 costs less than $120 in either D…
Unless you simply can't install more RAM without buying a whole new laptop. That's certainly the case for my laptop; its Intel i5 only can address 8GB max.
Memory is cheap, but buying a new laptop sadly isn't, especially when it's a decent development machine, and a step above standard consumer configurations.
