  1. In Win32, DLL's are "pre-linked" using a specified base address.
    2. 

  2. When the DLL is loaded, an attempt is made to place it at
    3. 

  3. that address.  If that address is already in use, a new base address
    4. 

  4. is selected, and the DLL subject to fixups.  Apparently, these
    5. 

  5. fixups are very slow, and significant performance gains can be
    6. 

  6. made by selecting a good base address.
    7.

  8. This document is to allocate base addresses to core Python
    9. 

  9. and Python .PYD files, to give a better change of optimal performance.
    10. 

  10. This base address is passed to the linker using the /BASE
    11.
