Re: [g-a-devel] at-spi2 first impressions

[Mark Doffman <mark doffman codethink co uk>]

Hi Matthias,

Thanks very much for taking a look at the project.

There was a glaring error in event dispatch that meant there was an idle
function running continuously.  I've just fixed and pushed the change.
(commit 30280d2d27b62c33ff)

This puts the orca / accerciser CPU usage back down to more reasonable
levels.

I'm seeing very high CPU usage when firefox starts up, and its taking a
long long time. (Although it does eventually settle down.) This
performance issue is even worse when looking at Devhelp. We have a plan
to fix this for Devhelp, and I'll take a look at what is making firefox
so slow.

Thanks again,

Mark
