[gentoo-user] Webkit-gtk yelp and dependencies

[Meino.Cramer]

Hi,

this morning it happens again: net-libs/webkit-gtk was
updated.
For me it means: For a longer time as convenient full
load on the all cores of the CPU of my GENTOO box,
higher CPU temperatures as usual and laggy desktop.

Hmmmmm...

I did a 
        emerge -cvp net-libs/webkit-gtk 

and got

Calculating dependencies... done!
  net-libs/webkit-gtk-2.12.5 pulled in by:
    gnome-extra/yelp-3.20.1 requires >=net-libs/webkit-gtk-2.7.2:4

>>> No packages selected for removal by depclean
Packages installed:   2088
Packages in world:    1099
Packages in system:   44
Required packages:    2088
Number to remove:     0


...so only gnome-extra/yelp needs the webkit-gtk.

I did a 

    emerge -cvp gnome-extra/yelp

and got

Calculating dependencies... done!
>>> Calculating removal order...

>>> These are the packages that would be unmerged:

 gnome-extra/yelp
    selected: 3.20.1 
   protected: none 
     omitted: none 

All selected packages: =gnome-extra/yelp-3.20.1

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

Packages installed:   2088
Packages in world:    1099
Packages in system:   44
Required packages:    2087
Number to remove:     1


...which seems that nothing needs yelp.

I myself use openbox and some gnome applications but
no gnome desktop/sessions management etc.

So it /seems/ that preventing recompilations of 
webkit-gtk is: Removing webkit-gtk and yelp.

But I better ask before I get into the situation
to be urged to recompile webkit-gtk...because I
was wrong...

Is the above ok or wrong or misleading or....

Thanks a lot for any help in advance!
Cheers,
Meino

quickpkg webkit-gtk before you depclean it, then you can restore with
emerge -k if you really need it after all.

You shouldn't get a laggy desktop these days. It was a problem a while back
(5+ years ago?) when fiddling with swappiness and cgroups or other stuff
i've forgotten was a thing.

Off the top of my head, these are useful;
CONFIG_CGROUPS=y
CONFIG_HZ_1000=y
CONFIG_HZ=1000

Maybe also try
CONFIG_DEFAULT_IOSCHED="bfq"

But your portage isn't...

You can also try setting PORTAGE_NICENESS in make.conf.

The old school fix for slow machines, increase or double the amount of 
memory.
  ( ... If already not maxed out. )
Memory should be cheap for that PC.

...my PC is seven year old...

The changes were software (kernel) based, so would apply to any hardware.
Its about contention rather than outright performance.
