In other words, don't do it on each request, just do it once when code file it is needed by is imported. Store the subsequent data in a global variable within the module. Preloading at process start can be done with mod_wsgi using WSGIImportScript directive: http://code.google.com/p/modwsgi/wiki/ConfigurationDirectives#WSGIImportScript This is akin to the PythonImport directive in mod_python.
