Not a word about the speed of the compiler itself.

It became a lot faster!

http://gcc.gnu.org/ml/gcc/2010-04/msg00948.html

"In general GCC-4.5.0 became faster (upto 10%) in -O2 mode. This is first considerable compilation speed improvement since GCC-4.2. GCC-4.5.0 generates a better (1-2% in average upto 4% for x86-64 SPECFP2000 in -O2 mode) code too in comparison with the previous release. That is not including LTO and Graphite which can gives even more (especially LTO) in many cases."
