What I experience when I have "Index source and header files opened in editor"
checked, is that every time I open a file, a "C/C++ Indexer" task appears in
the Progress view. This does not happen when I have the option turned off.
What is this task doing?
This task is checking the timestamps of the files and, if they didn't change, terminates. This is done on a background thread and doesn't affect the editor. Do you see a slowdown in the editor?
