Normal websites use large amounts of RAM Lately, on my MacBook Pro, visiting webpages has started to consume large amounts of RAM. Visiting websites like Stack Overflow, golang.org, golang playground, or gnu website causes my computer to perform very poorly since it runs out of RAM.

This occurs on both Safari or Chrome. Some of those websites are and most of them use no flash or any other plug in as far as I can detect.

What can be the reason for such a behaviour?
I have found out that the reason was some adware, malware infected my web browsers. They were making network requests initiated without my permission.

I have installed AdwareMedic and it completely solved my problem.
