Guido van Rossumcbc66761996-08-23 15:48:14 +00001In Win32, DLL's are "pre-linked" using a specified base address.
2When the DLL is loaded, an attempt is made to place it at
3that address. If that address is already in use, a new base address
4is selected, and the DLL subject to fixups. Apparently, these
5fixups are very slow, and significant performance gains can be
6made by selecting a good base address.

Tim Peters2a799bf2002-12-16 20:18:38 +00008This document is to allocate base addresses to core Python
Guido van Rossumcbc66761996-08-23 15:48:14 +00009and Python .PYD files, to give a better change of optimal performance.
10This base address is passed to the linker using the /BASE
11command line switch.
