Does GDAL utilize MMAP calls? Is this something you would consider as an enhancement?
Max, I am interested in adding mmap support the VSI*L IO API and seeing where it could be used. Libtiff can utilize memory mapping, and in some cases in the past I've seen noteworthy improvements in performance with it. I haven't used it for the last 11 years as it was difficult to use large files on 32bit systems, but with 64bit being so common that is less of an issue than it was. I might be quite particular about how memory mapping should be implemented. So you might not want to invest huge effort before discussing a proposed approach.
