Deadsneak Python 3.8:
>>> sysconfig.get_config_var('CFLAGS')
'-Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g
-fstack-protector-strong -Wformat -Werror=format-security'
Disco /usr/bin/python3.7:
>>> sysconfig.get_config_var('CFLAGS')
'-Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g
-fstack-protector-strong -Wformat -Werror=format-security -g -flto
-fuse-linker-plugin -ffat-lto-objects'
So the performance difference comes from optimization options.
