Well, it's a practical issue for me to run benchmarks for speed.python.org. Moreover, I like the idea of getting a fast(er) Python even when no advanced optimization techniques like LTO or PGO is used. At least, it's common to build quickly Python using "./configure && make" for a quick benchmark.

Do you mean comparison between current Python with PGO and patched
Python without PGO?
The hot attribute is ignored by GCC when PGO compilation is used.
