--- Comment #16 from Mathias Gaunard <mathias at gaunard dot com> ---
I opened bug #56746 a while ago which is somewhat related to this.
ftrack-macro-expansion is causing 50% increased memory usage in my case (C++
code with heavy usage of macros and templates).

Please also consider memory usage and not just performance.
