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

[Michael Whapples <mwhapples aim com>]

Hello,
Yes it is a single core pentium4. Could this account for some of the 
slowness when compared to at-spi on corba?


Using LXDE, the main issue seems to be locking up (well I think it is 
locking up) and these crashes.

As far as I know the packages are up to date releases (archlinux tends 
to be good regarding that).
