Couldn't one mmap() only a piece of the file at a time? I.e. mmap the first 10MB, then unmap it and map the next 10MB, etc.

The buffer cache would probably keep the memory that you munmap still around (if you touched it prior to munmapping). I think that's what Godfrey meant with "it will map the entire file into memory at some stage". Jonas _______________________________________________ Do not post admin requests to the list.
