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