 the mmap() is slow, because it invalidates the cache used by the processor
 for the translation of virtual addresses to physical ones. So mmap is a
 good thing if you call it once in the program, and the read many, many
 times. It is also good for sharing the memory overhead of reading a file
 between several processes. However, if one is creating and destroying mmaps
 all over the time, that is quite slow.
