Browser memory usage

I was curious why did Chromium “eat” my system memory and so I checked chrome://chrome-urls/ to see what’s there for memory usage debugging.

Saw chrome://memory-internals/ and checked it out. There’s the proof for browser tab and extension usage.

Tried closing and reopening some tabs, but before that I typed free -h to check memory usage.

$ free -h
              total        used        free      shared  buff/cache   available
Mem:           3.9G        1.9G        1.3G         53M        682M        1.8G
Swap:          2.8G        276M        2.5G
$ free -h
              total        used        free      shared  buff/cache   available
Mem:           3.9G        1.9G        1.3G         53M        684M        1.9G
Swap:          2.8G        275M        2.5G
$ free -h
              total        used        free      shared  buff/cache   available
Mem:           3.9G        2.0G        1.2G         58M        694M        1.7G
Swap:          2.8G        273M        2.5

The numbers were not lying. So if you working with a lot of tabs and extensions more RAM will benefit your system.

Similiar goodies are available also in Firefox. At http://kb.mozillazine.org/About_protocol_links you can see a list of internal about:* sites of Firefox.
