[Python.NET] Major speed change old 2.5 -> latest 2.5 build

[Barton]

Sounds like you are running in the interactive mode; ie opened python 
session interactively in a command prompt and typed

import clr

In which case;

help(clr) # would yield:

Help on module clr:

NAME
     clr

FILE
     (built-in)

DATA
     AddReference = <CLRModuleFunction 'AddReference'>
     FindAssembly = <CLRModuleFunction 'FindAssembly'>
     ListAssemblies = <CLRModuleFunction 'ListAssemblies'>
     getPreload = <CLRModuleFunction 'getPreload'>
     setPreload = <CLRModuleFunction 'setPreload'>

The Preload flag is set to True in interactive mode. Its function is to 
load the entire namespace of the default assemblies into the 
interpreter's namespace (mostly for debugging).

Please confirm that

clr.setPreload(False)

clears up your concern.

Thank you
