Re: [orca-list] for anyone on the bleeding edge

Hello,
Just some comments I have also noticed.
I believe opening local folders full of images and videos in nautilus might introduce a bit of delay not caused by the accessibility libraries but by the fact for local files nautilus generates and displays thumbnails for these filetypes by default. If you don't care about these or you can't see it you can go to nautilus Preferences and set the combobox Show thumbnails on the Preview tab to Never. I don't know why but I am suspecting the performance increase I can see after this new API has been introduced mostly happens for GTK apps. In Thunderbird I can still see lags when switching folders with a lot of messages inside. This is not verry significant in Firefox as I have no such big lists, tables whatever there. I can load a page on my work intranet with some 8000 + links, it takes about 7 seconds to render but I think this is expected. Also when calling links list on such a page it takes some 17 seconds from when I press alt+ctrl+k until I can browse the list. What I have to say that once the list is populated it is super responsive and the fact orca has to traverse the whole page hunting for links may really last that "long" I am afraid we are not going to see an update in this regard. Just to compare while there are more than 8000 links on my testing page there is just single list. When I press alt+shift+l the list with single item comes up instantly. 
I need to check Radio tray list with your bookmarks.
If you would like to see an app where this shows really big impact you might like to try gnome-contacts. I have got about 1080 contacts in there and without these patches list of contacts can hardly be navigable using the keyboard with orca running. After updating at-spi2-core and at-spi2-atk it starts to be usefull again. 

Greetings

Peter

Hi,
I've just updated Orca, at-spi2-core, at-spi2-atk and pyatspi2 to the
latest master from git.gnome.org, then I rebooted.
Now, I'm experiancing some improvement, but I want to verify that I'm
really using the latest at-spi2-core and at-spi2-atk.
So I did:
zahari zahari-laptop:~/at-spi2-core$ ls -l /usr/local/lib/ |grep libatspi.so
lrwxrwxrwx  1 root root        17 авг 16 00:18 libatspi.so ->
libatspi.so.0.0
lrwxrwxrwx  1 root root        17 авг 16 00:18 libatspi.so.0 -> libatspi.so.
-rwxr-xr-x  1 root root    565567 авг 16 00:18 libatspi.
zahari zahari-laptop:~/at-spi2-atk$ ls -l /usr/local/lib/ |grep
libatk-bridge-2.0.so
lrwxrwxrwx  1 root root        26 авг 16 00:20 libatk-bridge-2.0.so ->
libatk-bridge-2.0.so.0.0.0
lrwxrwxrwx  1 root root        26 авг 16 00:20 libatk-bridge-2.0.so.0 ->
libatk-bridge-2.0.so.0.0.0
-rwxr-xr-x  1 root root    627630 авг 16 00:20 libatk-bridge-2.0.so.0.0.0

So it appears I do, but is there a better way to check this, like to
ensure that Orca really uses this libraries?

So, I first opened Firefox, where I have 2189 Bookmarks. When I
navigated and opened the Bookmarks menu, the first time I've experianced
a freeze, but not the 2nd, 3rd and 4rd - so this should be Firefox -
creating the items.

Then I I opened Thunderbird, when I have over 130k e-mails in the All
Mail folder. It took some time til this folder loaded, but then I was
able to navigate freely through the e-mails. Then I've started to write
this message, but Thunderbird crashed, which could be very well on my
end, cause I experiance alot more crashes than the average Orca user
reports.

Then I opened the radiotray app, where I have a list with 24k radios,
organized by continent/country:
https://dl.dropboxusercontent.com/u/2445287/radiotray-bookmarks.zip
The navigation in the menu is really faster, but when I open the USA
submenu (5900 items), thinks become ugly.

When I went to my Dropbox folder in order to copy the above link, it
somwhat seemed that it loaded faster. So currently I'm playing around
and some folders load almost instantly, for example my Downloads folder
with 300+ items, but My Videos folder with 110 files took several
seconds, so I'm not really sure what happens here - maybe it's Nautilus
fault, cause my Home folder with 300+ items also loads instantly. Now,
when I opened the Videos folder for the 2nd time, it loaded much faster.
Yeah, it's Nautilus - even a folder with 7 subfolders can load slower -
may be it's calculating something.

Now Corebird. It's worth mentioning that some of Joannie's fixes made
things alot better here. Navigating the list was fast, but whenever I've
changed the focus - this was freezing everything. Now, I'm on 798 items
and I'm able to open a link (which opens Firefox) and to return to
Corebird without freezing. When Corebird releases this items however,
for example when I go to the first tweet and change to the Mentions tab
(Alt+2) Oor refresh the current tab (Alt+1), there is a small freeze
with 800 items, none with 100.

Ok, I've challenged it now - I invoked the List of links in Firefox
(Alt+Shift+k), which produced 3291 items. I can see when the dialog
appeared, and after that it took at least 10 seconds for Orca to be able
to read those items.

Very good job - thank you very much. This made me very happy today.
Please test with radiotray with the bookmarks file I gave you and the
Orca's Links list in pages with thousands of links, which appears to be
the most hard for now, and see if you could decreese the delay.
If I spot anything else - I'll write to the list.

Best wishes,
Zahari

Sorry, resending to the list

I have begun testing, using your pkbuild.
No problems so far, and gnome-logs works as expected. well, let's see.

Hello,
Thanks once again for this. My full comments can be found on the bug
it-self however I can't resist and I have to also comment here that
this is really significant update. Lags can now be hardly noticed on
my configuration running gnome apps.
If anyone would like to get one time tweaked PKGBUILD scripts for
trying this on arch linux and friends, they are attached.
First build and install at-spi2-core, then install at-spi2-atk and
finally relogin or reboot or whatewer you wish in order to get to use
them.

Greetings

Peter

hi
Thanks a lot, mike! I'll pull immediately and test. If  this works,
it'll be amazing and make gnome 3.18 that much better!
Thanks

Hi all,

I just committed a change to at-spi2-core and at-spi2-atk that we've
been considering making for a while (see
https://bugzilla.gnome.org/show_bug.cgi?id=650090 for details).

There is some risk in making this change late in the 3.18 cycle.
However, it reportedly fixes various performance issues with large
lists and such, so it seemed worth making. However, testing would be
appreciated. To test, either pull the latest at-spi2-core and
at-spi2-atk from git or wait for the 3.17.90 release (I plan on
rolling a release on Monday).

Thanks,
-Mike
