[g-a-devel] At-spi over dbus performance.

[Luke Yelavich <themuso ubuntu com>]

Hi all
I tested at-spi via dbus a couple of days ago, and can certainly notice the performance difference with some things, and not so much with others. The one area I particularly notice a difference is when reading the pidgin buddy list with orca. Reading down the buddy list takes a while to speak an individual item, say half a second. This gets progressively longer as I get further down the list.

I am wondering whether there is any code being worked on outside the main at-spi2 git trees to address performance. The Ubuntu desktop team would really like to switch to using at-spi over dbus for Natty, but performance is one area where we feel needs improvement if we are to make that choice. The Ubuntu desktop team may be able to provide extra help in solving performance issues in the future.

I notice on the at-spi dbus migration page that nothing specific is mentioned about performance. What has been considered to improve things? Perhaps I can let the Ubuntu desktop team know what is being considered, and better ideas could be put forth.

Thanks

Luke
