hi
SUre thing, will do. I'll have to switch machines. I'll file two debug
logs, if that's ok. One from her machine, where the lag is worst, to
mine where it's still there but not as bad.
Thanks

Hey Kendell.

Sounds like a potential event flood and/or pyatspi caching a very 
large tree, similar to that Thunderbird lag. If you file a bug with
a full debug.out I can try to pin down where the bottleneck is.

Thanks! --joanie

hi all. This might be a bit long, so settle in with a cup of
coffee or something. I seem to be in an unusual situation with
orca. I just bought my fiance mellisa an ssd for her computer. As
a result, her system is wildly out of balance. She has a really
fast ssd, but the same slow intel dual core 2.0 ghz processor,
and same old intel mobile hd graphics. As a result, orca is at
times extremely responsive and at tiems nearly unusable as it
struggles to keep up, often stuttering "window. deskt window.
desktop frame. Icon view layored pane" as the processor catches
up with the very fast ssd. I'm writing in to report some severe
lag I'm experiencing in orca when navigating list boxes, tree
views, or tables. Specific examples are below, but any list will
do this. In gnome-initial-setup, when trying to navigate the list
of locales and keyboard layouts, orca's lag is so bad it takes
somewhere between five and ten seconds to respond to a key press.
That is, I press the down arrow key, wait ten seconds to hear the
next keyboard layout or locale. In nautilus, when entering a
directory with hundreds or thousands of files in it, orca's
performance slows to acrawl. It can take quite a while for orca
to react to key presses. This seems to be orca specific, because
I can see the the focus move visually to the next file
immediately. In the gnome overview, when typing, I can see the
search results rapidly change as gnome narrows down the results.
I can see gnome highlighting the results, but sometimes orca
doesn't speak them right away. If there is only one result,
sometimes orca doesn't speak the result at all. Any application
that has lots of items in a tree view will lag a bit with orca
but it's really not that bad. What is concerning is that after a
while, orca will stop announcing the treeview items, but simply
saying "tree" I'm not certain exactly when this happens but it
always does if the tree view is long enough. A good example is in
accerciser and mime editor. These are *not* complaints. Joanie, I
really hate to ask you to do this since I know you're busy with
gnome 3.16, but would you mind looking into this? Is this even an
orca issue, or is her system so wildly unbalanced that the ssd is
doing it's job but the rest of the system components just aren't
fast enough to keep up? If it helps at all, the lags in very long
lists, tables and tree controls happen on my system, and almost
as badly as hers, even though my system is several times more
powerful. Quad core processor, 8 gb of ram. Should I file a bug
against orca, providing debug logs? Are these maybe gnome issues?
I'm sorry I'm not clearer, I don't exactly know what's causing
orca's lags, so I'm being as clear as I can. As a final note,
both systems are running identical oses. Both running fedora 21
with all updates applied as of this morning. Thanks for reading
