This is getting insane. Please learn how to use madvise and posix_fadvise and let the kernel deal with paging. The kernel knows everything about the underlying hardware; the application does not. > Memory is used as a cache. This is not broken. This a valid use. By paging the data manually to the disk, the only thing you are achieving is duplicating it at the time of reading/writing. Please learn how to use memory pages and stop telling people you know better when it is obvious you don’t know what you are talking about. -- .''`.
