Mac Intel Ventura 13.6 command line tools

Hello,

Using Mac Intel Ventura 13.6 I upgrade to latest command line tools that provides clang 15.0.

Unfortunately the applications compiled with this last update are running 4 at 5 times SLOWER . Has any one the same observation ?

Here the command line :

g++ -Ofast -march=native -flto -funroll-loops -DNDEBUG -o a myprog.cpp

So I reverted to clang 13.0 to have an acceptable performance.
