Hi this highly depends on you impl so using a profiler may give you
hints. One possibility could be to give the runtime eclipse more
memory (xmx) other could be to improve scoping or the grammar itself
(no backtracking)

Hi,
Perhaps one possibility is creating a new file type, which represents
the global view and only let the generator for this file update
output.c. For this file type there will typically only be one file. This
file should have an explicit reference to some object in each of the
other files, so Xtext knows of the dependency and can trigger a
re-generation.
