| In Win32, DLL's are "pre-linked" using a specified base address. |
| When the DLL is loaded, an attempt is made to place it at |
| that address. If that address is already in use, a new base address |
| is selected, and the DLL subject to fixups. Apparently, these |
| fixups are very slow, and significant performance gains can be |
| made by selecting a good base address. |
| |
| This document is to allocate base addresses to core Python |
| and Python .PYD files, to give a better change of optimal performance. |
| This base address is passed to the linker using the /BASE |
| command line switch. |
