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:

update-python-modules
UPDATE-PYTHON-MODULES(8) System Manager's Manual UPDATE-PYTHON-MODULES(8)
NAME
update-python-modules - byte-compile python modules
SYNOPSIS
update-python-modules [options] [package.public [...]]
DESCRIPTION
The update-python-modules command is part of the python-support bundle.
update-python-modules is responsible for the byte-compilation of python modules. When used in byte-compilation mode, it will byte-compile
modules references in the files given on the command line. When used in installation mode, it will byte-compile them once for each
installed python version, and will make them available for all of them.
At each invocation, with or without arguments, update-python-modules will check for installed python versions, and will build or remove
modules according to new or removed versions since the last time it was run.
ARGUMENTS
Arguments must be files or directories located in the /usr/share/python-support directory. Depending on their extension, they are treated
differently.
package.public
A file listing public modules to install for each version. These modules must lie in /usr/share/pyshared or /usr/lib/pyshared.
package.private
A file listing private modules to byte-compile for one Python version.
package/
A legacy directory hierarchy of public modules. The C extensions and portions that change with the Python version are to be found in
/usr/lib/python-support/pythonX.Y/package/.
package.dirs
A legacy file listing directories where to find private modules.
OPTIONS
-h, --help
Show summary of options.
-v, --verbose
Detail all actions while they are performed.
-b, --bytecompile
Only accept to work on private modules. When given this option, update-python-modules will fail if passed references to public mod-
ules.
-i, --install
Only accept to work on public modules. When given this option, update-python-modules will fail if passed references to public mod-
ules.
-c, --clean
Clean modules instead of installing them.
-a, --rebuild-all
Rebuild all private modules. This is necessary when the default python version was changed, for example.
-f, --force-rebuild-all
Clean all modules (public and private), and rebuild them.
FILES
/usr/lib/pymodules/pythonX.Y/
These directories contain the byte-compiled modules for version pythonX.Y.
