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?
In: 3000
Besides, it may sound counterintuitive, but unlike, say, disk space, ram is meant to be used as much as possible
You don’t get an advantage clearing ram to have “available memory”, more likely you lose efficiency flushing ram unnecessarily
So programs (not just browsers) cache their procedses to ram since they can retrieve it much more efficiently than reloading from disk. And system will flush unused cache when other processes need it
Finally, that ram usage is not webpages being cached but memory used by the browser to work (rendering, analyzing, moving stuff around, code, etc)
