why do web browsers use so much ram, while the average size of an entire webpage is 2mb?

794 views

From what I understand, one could cache 100 web pages (obviously, 2mb is average, but there are much smaller and much larger than that) in about 200mb. 1GB could cache literally 500 web pages.

How come web browsers use so much ram then?

If you look at your operating system’s memory usage and see the browser taking so much, part of it is because nothing else has come along to reclaim it.

ELI5 moment: Imagine a kid playing outside in a field of snow. Everywhere he leaves tracks are “his”, because nothing else has come to reshape the snow, even though at any given moment he’s only playing in a few square feet. Only once another force, like a plow comes along, and reclaims the area does it not count as “his” anymore.
