| 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.
|
|---|
| 7 |
|
|---|
| 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
|
|---|
| 11 | command line switch.
