C++ is indeed generally faster, but it really depends on a lot of things which program is faster when accomplishing a certain task. The following things may play a role: memory management, the way certain data structures are supported at low level, hardware. I have always been intrigued by the results from the following site:

python2.7-config
PYTHON-CONFIG(1) General Commands Manual PYTHON-CONFIG(1)
NAME
python-config - output build options for python C/C++ extensions or embedding
SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --help ]
DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically
(at run time) into the interpreter.
OPTIONS
--cflags
print the C compiler flags.
--ldflags
print the flags that should be passed to the linker.
--includes
similar to --cflags but only with -I options (path to python header files).
--libs similar to --ldflags but only with -l options (used libraries).
--prefix
prints the prefix (base directory) under which python can be found.
--exec-prefix
print the prefix used for executable program directories (such as bin, sbin, etc).
--help print the usage message.
EXAMPLES
To build the singe-file c program prog against the python library, use
gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp
The same in a makefile:
CFLAGS+=$(shell python-config --cflags)
LDFLAGS+=$(shell python-config --ldflags)
all: progr
To build a dynamically loadable python module, use
gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so
