Description _ rkubacki 2005-09-09 13:54:42 UTC

This method is called >2200 times during startup and always tries to get "name"
attribute of underlying FileObject. If there is no such attribute it gets the
name of fileobject and this happen in almost all cases (unless you customize
some setting like add new AutoUpdate). Searching of attribute is not the
cheapest operation as it goes through our MFS and assembles name of file.

We should at least try not to check if there is the attribute every time. This
can save >75% of calls to FO.getAttribute from this place.
