Memory mapped files are much faster provided that the system has adequate RAM to cache the whole file, and the file is read repeatedly. Computer RAM has become quite cheap so computers are commonly comming with multiple gigabytes of RAM. This changes the equation.

Every modern kernel will cache file content in memory no matter what access mode is used. However, ordinary access modes don't have the pathological thrashing problem that memory-mapped access does.
