| Guido van Rossum | cbc6676 | 1996-08-23 15:48:14 +0000 | [diff] [blame] | 1 | In Win32, DLL's are "pre-linked" using a specified base address. |
| 2 | When the DLL is loaded, an attempt is made to place it at |
| 3 | that address. If that address is already in use, a new base address |
| 4 | is selected, and the DLL subject to fixups. Apparently, these |
| 5 | fixups are very slow, and significant performance gains can be |
| 6 | made by selecting a good base address. |

| Tim Peters | 2a799bf | 2002-12-16 20:18:38 +0000 | [diff] [blame] | 8 | This document is to allocate base addresses to core Python |
| Guido van Rossum | cbc6676 | 1996-08-23 15:48:14 +0000 | [diff] [blame] | 9 | and Python .PYD files, to give a better change of optimal performance. |
| 10 | This base address is passed to the linker using the /BASE |
| 11 | command line switch. |
