I dunno, having a large address space could be useful if you work with large or lots of memory mapped files?

- AstralStorm 8y agoOr you could use large file support and not mmap everything. It is probably faster too and puts less pressure on overcommit mechanism.
- Hello71 8y agofile-backed mmap is by definition not related to overcommit, because the memory is committed by the file.
- geocar 8y agoSure. Parts of my (multi-process) application can use 64-bit pointers and parts can use 32-bit.
