[Glade-users] [glade-users] Glade 3.10.0 is running a bit slow

[tristan.van.berkom at gmail.com (Tristan Van Berkom)]

Thanks !

I loaded up the file you sent and it appears that most of the time can
be tracked
down to:
  a.) Glade handling events, which results in showing a hidden editor
page in the
       GladeEditor widget...
  b.) When looking at the callees of glade_widget_event() one notes that
        most of the time spent in there is spent in gtk_css_provider_get_style()

Possibly the problem is around resolving things that should probably already
have been cached the first time around (i.e., how come we spend time searching
and matching css styles for the widgets in the editor if they've been created
at least once ?)

One thing I have never tried personally, is a GTK+ 3 installation in /usr and
a theme installed, is this why I am not getting such bad performance issues ?

Is your test case built into /usr  ? maybe that doesnt matter... do you get
the ugly default native GTK+ theme or are you picking up some kind of
elaborate and beautiful theme while running Glade ?

If so, can you try running Glade in a naked environment, with no fancy
css applied and report back if the problem persists ? (or if it's less
bad ?)

Thanks alot for your help, I'm trying a GTK+ master build now to see
if this is a possible regression... I havent been paying attention to
GTK+ releases lately... maybe everyone is running something more
recent than 3.3.3.

Cheers,
          -Tristan
