This is true. There is a customisable threshold ggtags-oversize-limit. I
used to test ggtags regularly on the Linux kernel source and it was very
fast IOW I was not disappointed.

If source files are changed outside emacs for example by git pull,
ggtags will notice and reindex. For example if M-. jumps to a location
that is off I often M-, and then M-. again to trigger reindex
immediately.

HTH,
