I came to Ubuntu 16.04 from Mint 17.3 (and Ubuntu Mate 15.10), and I'm shocked with the memory usage of Ubuntu 16.04.
With a clean install, 16.04 used about 650+ Mb RAM, and after 1 or 2 days, after when I've installed most need apps for regular usage, 16.04 uses ~ 1GB at idle, and climbs to 1.5GB only with 4 or 5 chrome tabs.
Then I use a terminal tool to check for memory ( I use
ps_mem here) - and the memory here is significantly lower than which showed in System Monitor:
So, my questions are:
- Which tool shows the right memory usage: System Monitor or
- Why is Ubuntu 16.04 using so much memory?
