Re: [orca-list] lagginess in latest pamac

hi
Yup, that did wonders. It's a lot faster now. I'll be sure to update all
my machines tonight with the newest orca.
Thanks a lot for the great work

Yeah, that helped. Thanks! Hopefully fixed in master and the gnome-3-20
branch. Could you please verify? (Yes, I know, now you have to wait for
more updates to appear. But since the GNOME 3.20.2 release is this week,
hopefully you'll have some soon.)

By the way, if Mellisa is not a braille user, she might wish to disable
braille in Orca's preferences. If she is, never mind. But your debug.out
indicates that Orca is generating braille but is not able to communicate
with brltty. While I've greatly improved braille performance over the
past year or so, if braille is enabled, Orca will still do the work to
generate it. If the result will never be used, she can shave some time
off Orca's processing by disabling it.

hi
Got a debug log from mellisa's machine which has both linux and windows
on it. In this one, I installed all the updates and then turned orca off
using the shortcut. There was quite a bit of lag in this one because
there were 17 updates available, and I installed all of them. First, I
went through the list of updates, then hit the apply button with alt+a.
Attached below. And when I said "it's not good that even you couldn't
install my vm" I meant it as a complement. You're a lot more technically
savvy than I am, so there must really be something wrong with sonar if
you can't figure it out. The debug file is compressed because it's over
a megabyte.

Thanks

I don't think it would help. I set up the Manjaro VM to be pretty
under-resourced. The source of the problem is very likely one or more of
the following:

1. Event flood
2. Orca examining a bunch of things inefficiently
3. AT-SPI getting slammed by a bunch of new objects

What you'll notice all of those have in common is a bunch of stuff. And
the first and third are related to a bunch of new or changed stuff. So
we need Orca running and capturing a full debug.out when the bunch of
rows in that table get added or resorted or whatevered.

And because I have committed a number of performance-related changes to
both master and the gnome-3-20 branch (I'll do the 3.20.2 release before
too long, but it's not done yet), you'll want to capture a log using one
of those.

Thanks again.

hi
Would it help if I got one off of a slower machine? I've got a laptop
with about half the specs this machine has, and later tonight I can get
a debug log and send it to you. Yeah less than a tenth of a second isn't
enough lag to complain about lol.
Thanks

Thanks. But I think I'll need one with lots of lagginess. Don't update
for a while, I guess. <smiles>

The most slow presentation I see in your debug.out is 0.0851 seconds.
And during most things, Orca was much faster than that. I of course
would like to improve slowest one, but when the total time Orca takes to
do all its work and present your new location is less than one tenth of
one second, it's hard for me to know where to debug and try to improve
things. If you can capture a log in which Orca takes a noticeably long
time, then I can look at see if it's long/laggy because Orca is not
processing things efficiently.

hi
No problem, attaching one now. That's not a good sign that even you
can't get sonar to boot on a virtual machine. I've got to fix that, but
I don't have the slightest clue about what could be going wrong. Anyway,
debug file attached. I couldn't get orca to see the table since there
were no updates to install, but it was a little laggy. Not as bad as
usual, but the lagginess seems to depend on how many updates there are.
If only a few, there's only a slight lag. If a lot, there can be a long
lag, but it never gets horrible It is noticeable, but it never gets
unusable.

Thanks

Hey Kendell.

I guess I will need a full debug.out.

I tried to set up a virtual machine with sonar-gnome-edition-16 but it
doesn't fully boot. (Gets as far as "Started User Manager for UID
1000....") So I set up a virtual machine with Manjaro with XFCE, enabled
accessibility, installed Orca (from their packages, so 3.20.1). And that
update manager doesn't give focus to the table, but if I start tabbing,
Orca doesn't take several seconds to respond.

If you could capture a full debug.out using Orca master, that would be
great. Thanks!

hi all
Steps to reproduce. Open the software updates tool in manjaro, which you
can do by either typing in "software" in gnome or opening it in the
menus in mate. If you use sonar, there's an icon on your desktop you can
click on. You will first hear "frame. Followed by how many updates you
have to install. Orca is focused on a table with the updates in it, but
it takes several seconds from the time orca says how many updates are
available before it mentions "table" and you can navigate. I don't know
if joanie will be able to reproduce this since she uses fedora, but I
can either provide her a debug log which I'd be happy to do or she can
download the alpha image of sonar, which has the latest pamac on it to
try to reproduce with. I'm trying to figure out whether this is an orca
issue or a pamac one. Can anyone who uses sonar confirm this?
Thanks
