Re: [orca-list] Very slow performance with orca and at-spi2



Hi,

sending this back to the list.

May be what I initially said was slower than what I am now getting,
but I have switched the desktop to LXDE and don't know if that might
be impacting.

I wouldn't really expect it, I'm using fluxbox here.

As it was very early on in my upgrade, may be I was just unfortunate
in getting many lock ups. Regardless of that, it certainly is slower
than the corba version of at-spi.

 Ok, interesting, that wasn't what I've seen and I'm not really sure
 why.  The only thing that comes immediately to mind is the package
 being out of date, or maybe that you are on a single core machine,
 which I would expect would make things slower.

Also as I mentioned in another message I am also getting some
crashing of orca as well.

yeah, no idea about that either.

Hello,
Archlinux has now moved gnome 3 into stable and so I have upgraded
my desktop to gnome 3. However I notice some extremely poor
performance issues when using at-spi2 through dbus. One example is
when opening thunderbird (3.3a2) and also when opening a message in
thunderbird 3.3a2. In fact with the opening of a message, the
performance is so bad, I don't know whether it is locking up or not
as I have never actually got to read the message on my system
(waited for over a minute).
ok, I just downloaded a nightly and tested with that since I'm not
normally a thunderbird user as my mail headers tell you ;)  I'm noticing
some bad performance doing these things, but not nearly as bad as you
describe, I have 750 messages, and thunderbird starts in maybe 30s and
opening a message takes 15s (those numbers are my wild gues not timed at
all).  I don't really know but I suspect this will be improved a bit
when at-spi2 start sending events over direct connections (this is
something I've been meaning to look at doing).

If I set the gconf key to enable at-spi to use corba, the
performance is back to what I am used to.

There are other cases where at-spi2 through dbus seem to lock up,
eg. when opening regional settings in gnome 3, epiphany, etc).

Does anyone else notice these issues?
well, I don't have any of these apps installed, but I think I've noticed
some random locking up.  It smells vaguely like its related to keyboard
events, but I have no reliable way to reproduce this.
