Public bug reported:
Hi,
my computer is very sluggish for a good five minutes after thawing from
hibernation.
Booting the system and the thawing process in itself seems to run fine :
the console displays the progress of reloading contents into RAM at a
satisfying pace, then the lightdm unlock interface displays.
>From this point on, things become strange : the computer has an constant
and intense hard drive activity and applications do not respond to input
in a swift manner (moving the mouse cursor works in "real time" though,
and the clock, which displays seconds, also works almost normally).
This reminds me of what happens when you set focus back to an
application that had been paged to swap : it is irresponsive until it is
back in RAM. Except this happens for all applications at once.
I experienced the problem today again. The current RAM usage is 7.2 Gio
/ 15.6 Gio and swap usage is 4.2 Gio / 31.3 Gio.
Main memory usage is :
firefox 3.4 Gio
firefox (other instance) 1.7 Gio
thunderbird 624 Mio
xfwm4 213 Mio
Hibernation with TuxOnIce did not induce this problem (I am not using it
currently due to mismanagement of video drivers).
