I've noticed that the performance of indentation can degrade
significantly in files with large amounts of quoted text that contain
syntactic elements. For instance, I have a class that outputs a C++
class definition that is stored as a string in my Java class. I have
noticed very poor performance on that file and files like it. However,
I haven't experienced poor indentation performance in other files. I
never tried to figure out what the solution was since it didn't bother
me that much, and the vast majority of files were unaffected.
Another possibly related problem I've experienced is that when editing a
Java file that used a two space indent (which is different than my four
space indent), it would take an unusually long time to indent a comment
(using the c-electric-slash functionality). I wondered if the different
indentation level wasn't causing it to do more work to figure out what
the proper indentation was.
