This is because pcmanfm is not entirely accessible. If you use the arrow keys to select a directory in the left tree view, and press F6 to switch to the individual folder/file view in the right panel, you will notice that you do not get any feedback from Orca.

Unfortunately due to the way the accessibility framework works, anything that requires a lot of accessible objects to be created, such as a big website, a folder with a large amount of files in it, etc, will make the system churn a bit, because the accessibility framework has to query all those objects in the window, and get information from them for accessibility. The best we can hope for is for the performance of at-spi over dbus to be improved, something which is being looked into.
