But, in theory, an operating system can create a table of the sectors used by the loop file, and use that table instead of calling the filesystem libs to access the file. The file itself is static, it doesn't change in size nor location, at least while mounted: thus you really do not need to access the filesytem structures.
If the file is not fragmented, then it should be as fast as a real partition.
That's a nice trick. I'd guess that it doesn't work with all file system types, as this assumes that the underlying file system doesn't somehow move the data along. I'm unsure if any does, but e.g. via - I know, a bad choice - NFS, the loop module couldn't rely on this assumption.
