Assuming infinite memory, it will never be faster than reading whole strips. But TiffReadScanline may have access which allows it to (often) use memory more efficiently than reading the whole strip. Libtiff also supports a strip-chopping feature which may allow large strips to be presented as a set of smaller strips (depending on compression type).
