Tab Hibernation

Hi,
I enabled the hibernation flag in Opera on my Ubuntu machine. Description I found in one f the forums is:
#tab-hibernation – If a background tab is inactive (does not load anything including XHRs, plays any media, plug-in is not streaming any data, or a script is not changing page’s title/favicon) for 40 seconds its process gets suspended and swapped out (causing process memory usage drops significantly) ...
I am waiting for hours already but non of the tabs seems to be hibernated (process count does not decrease, memory usage stays the same). Does anybody succeeded in using this feature? Or maybe I am checking it wrong ... I don't know.
My system is:
Version: 30.0.1835.125 - Opera is up to date
Update stream: Stable
System: Ubuntu 15.04 (x86_64; Unity) -

works here on win7 x64
tab mem consumption dropped from 50 MB to 600 KB (test page)
I tested it in developer version, but I was using tab hibernation probably since last year when introduced, so I don't think it's about builds
More likely depends on OS (working/not working) -

Ghm. Thanks for sharing info. Maybe this feature does not work on linux at all. It is very little documentation about it. Would be interesting to hear comments from Opera developers themselves.

This feature should work fine on Linux, it's just much harder to see, since we can't manually specify the process for being swapped out. What you should see is that when you're using other applications that take a lot of memory, your computer will not slow down - the inactive Opera processes will be swapped out by the OS, expensive page-ins of those processes will not be needed, and the memory can be reclaimed by other applications.
