[orca-list] ff3 slow navigation response

[Christopher Moore <christopher h moore verizon net>]

I'm reposting this with a smaller debug output to avoid being bounced.

Hello,
I've recently installed orca from svn trunk, and my ubuntu gutsy system 
seems to be running ok.

I've been using ff3 and am experiencing slow response when attempting to 
navigate web pages using the orca gecko navigation keys.   

My wife, who is sighted, can navigate the page easily with the mouse, 
and orca seems to do a good job of announcing the current location on 
the page.  This in itself is a major step forward from ff2 where orca 
wasn't able to keep track of what was going on.

I'm attaching a debug file from a simple test.  First, I brought up a 
web page.  Next I enabled orca deubugging and restarted orca.
Now for the test:
I first entered 'h' to search for headings.  If you're looking at the 
debug output, you can search for "Wrapping to top" which is the result 
of the command.  A couple line above this you see the time (571.69) when 
the keystroke process began.  I don't see a time when the speech/braille 
was actually output, but I entered the next keystroke 'o' as soon as 
output was spoken.
The next time (604.97) is approx 33 seconds later.  So what was 
happening during those 33 seconds?

After the 'o' which occurred at approx 605, I switched applications with 
alt+l at approx 619 seconds.  So the 'o' took approx 14 seconds.  

My question is basically two-fold.  
First, why is orca response to navigation keys so sluggish? and
Second, what plans are in the pipeline  to improve the user 
experience?

I'd like to help resolve this particular issue and feel I can make some 
contributions in the areas of programming and testing.

Chris
