Description Mike Gorse 2010-11-18 07:58:55 UTC
AT-SPI2 is significantly slower than at-spi-corba and so is not really usable.

Currently, the main issue is that pyatspi2 is written entirely in Python and uses the dbus-python bindings.  Having a C core with gobject introspection should improve things significantly.

Having peer-to-peer dbus connections should also help.  There is currently a branch called p2p for this in at-spi2-atk and pyatspi2.  I had not merged this with the main branch because it needed a dbus-glib fix (FDO#30574).  This fix is now part of dbus-glib 0.9.0.
Comment 1 Mike Gorse 2011-04-19 11:50:37 UTC
Both of the aforementioned changes are now in the released AT-SPI, and AT-SPI2 is significantly faster now, so I am going to mark this bug resolved.  However, method calls are likely still slower than they were with AT-SPI-CORBA, while some tasks (such as retrieving an object's children or states) are likely faster because they rely entirely on cached data.
