Yes -- this is what I'm talking about.

I think all this discussion has missed the original question.
Quite simply, is there any way in which the SQLite *source code* could be changed in order to get better performance on 64 bit machines. If there is then following questions should be answered:
- Has it already been done (or should it be done)
- Can the changes also be used on a 32 bit machine, or is the codebase forked
One thing you can do on 64 bit machines is memory map entire files, so there is no explicit need for page caches and things like that. This is possible due to the larger address space available which would need to be larger than the file size. (On 32 bit machines programs typically can only memory map files under 2GB in size).
