Comment 11 for bug 1572801

I installed new fresh-install ubuntu 16.04 64bits
and noticed high ram usage,
in my case, rapidly going to swap, so making ubuntu slow, with little work load.
Previous versions (I always used 32bits on this machine) didn't swap on normal daily usage.

I'm on an relatively old Dell Latitude D530
with 2gb ram
processor Intel Core 2 Duo @2.0ghz x2
graphics intel 965gm (system configurations -> update -> additional drivers says it's using the proprietary intel-microcode firmware for intel cpu but it wasn't activated on the previos ubuntus 32bit versions I used in past).
I installed (from ubuntu software): dropbox (which is running, automaticly from start-up) ,
and also synaptic, gimp, inkscape, virtualbox (includes dkms), kazam, pulse audio volume control, viewnior, linssid (wich are NOT running).

So now, I rebooted, opened firefox with only this tab, and system monitor, which is indicating 1.1gb ram usage.

So I tried deactivating the proprietary intel-microcode firmware for intel cpu,
but it seems to make no difference,
Anyway, I will reboot now, and if I see difference, I'll write.
If I can help, maybe some log or test, please let me know.
