Show HN: Save Memory in Google Chrome

Isn't 95% reduction claim a bit too bold? It is widely known that standard measurement of Google Chrome's memory consumption with task manager is wrong because it doesn't take data sharing between processes into consideration. How was the 95% figure produced?

He has 21 tabs opened, by reducing it to 1 tab, he has saved 20/21 lots of memory, ~~ 95% saved.

Assumptions: each tab uses same memory; no shared memory (or shared memory equally divided between all tabs), every user has around 20 tabs open given the first 2 assumptions hold true.

To me, the 95% is a magic number.

This is the same question I have. Memory usage is notoriously tricky to measure because of shared libraries and the like. So a simple figure like 95% doesn't end up meaning much at the end of the day. chrome://memory may be a good place to start.

Ninja edit: note the disclaimer at the bottom of chrome://memory:

    (Note: Due to memory sharing between processes, 
    summing memory usage does not give total memory usage.)
