--- Comment #11 from Rene Koecher <rene.koec...@wincor-nixdorf.com> ---
Hi,
I want to chime in on this - is there anything new regarding the issue?
The current state marks it as UNCONFIRMED however there is some definite
performance loss even in the current 4.9.1 and 4.9.2 gcc releases.
My employer switched to gcc 4.9.1 recently and our codebase (mostly C++, heave
users of stl / boost) has almost doubled it's compile time.
We're up to 60min for a clean compile - and that is with ccache enabled.
Plain, no-ccache compiles are even worse.
Compiling with -ftime-report shows that g++ is spending significant ammounts of
time in the 'parsing' stage (mostly between 1.8 and 2.8sec/per file).
Currently we're using 4.9.1 on CentOS 5 (custom build) but I also confirmed the
same increase in compile time on a Gentoo and Debian system.
