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

I should actually point out that turning off the default GNOME 3 doesn't
"fix" the issue, it just makes the lag less significant. Sounds like what
you experienced Tristan--about half a second.

Also, I posted my last message with the wrong email, not sure if it went
through. It's shown below:

Ding ding ding ding!

I'm using GNOME 3 on Fedora 16 with the GNOME 3 default theme
Adwaita. When I switch the GTK+ theme to Raleigh using Gnome Tweak Tool the
problem is goes away. I'm not up to speed on how themes work in gtk+ 3 but
I believe Raleigh does not use a theme engine.

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

Hey, I'm going to attach my callgrind output in case one of y'all know

what

you are doing better than I do. I started glade with`

--instr-atstart=no`,

added a button and a label to the window, and then turned it on with
`callgrind_control -i on`. I then selected a different widget and

turned it

off with `callgrind_control -i off`.

I don't really know what I'm looking for the KCacheGrind just yet and I
don't have any more time to dig around today, but all these graphs ans

such

look pretty awesome.

I've got 4GB RAM and a dual core AMD64... plenty fast. I have a lag of

1.5

- 2 seconds based on the very accurate and scientific "one

mississippi..." approach. ;)

I'll see if I can tinker with valgrind sometime in the next week or so

if

I have time.

I've asked the same question here about a month (?) ago, and there

was

no
definite answer,


I just tried building a few versions here, and I have pretty much the
same lag
from GTK+ 3.0.9 to GTK+ 3.3.3, I havent tried any versions before

3.0.9

or
after 3.3.3.

I have a very old laptop here (about 5yrs old and chugging along,

every

second time I power her up she decides to find the operating system...
and
grub happily shows up).

Running 64bit linux here, with this processor:
  AMD Turion(tm) 64 X2 Mobile Technology TL-58

Its dual core, each of them dishing out about 800Mhz.

Admittedly selecting a new widget is annoyingly slow,
probably around half a second or a bit more, just enough
to make you feel annoyed, definitely nowhere close to
a 2 second lag.

Currently I'm really busy with other things and can't be
bothered... so I'm looking to you guys to profile it and find
out where is the bottle neck, where are we spending the
majority of this time ?

In size requests ? is it a silly Glade bug ?

I recommend valgrind with the cachegrind tool, output
is quite pretty when viewed with kcachegrind.

And it doesnt require hacking your kernel like other modern
profilers do...

Cheers,
             -Tristan


apart from it probably being GTK's and not Glade's fault.
I just opted to actually coding my interfaces until this gets
corrected.

Sorry I couldn't be of much help,
Matej

I've seen a few other people mentioning this, but, I can't find any
bugs
or information. What I'm seeing is that when you select from one
widget to
another (either in the editor or the inspector) the UI blocks for
about 2
full seconds. This only happens when selecting a widget of a

different

type
than the one currently selected (eg. selecting a GtkButton and then
another
GtkButton is fast, but then selecting a GtkEntry is slow).

Any insights?
