You're comparing the Python that has been built by your distro with a certain compiler and certain optimization flags, with the Python that has been built by Buildroot using a different compiler, with different optimization flags. > the difference between glibc and uClibc be so huge for python? I don't know. Maybe the dynamic linker is slower, maybe some other parts of the C library are slower, but I'm not sure, it needs investigation. Is is reproducible even after the first run? Are you running the same kernel, with the same configuration? Your two environments are really different, so it's very difficult to make correct comparisons and draw conclusions from them.
