Probably this is encouraged by documentation like this:
The memory mapping interface is described in Memory Management
Interfaces. Mapping files is the most efficient form of file I/O for
most applications run under the SunOS platform.

People often think about the main benefit of mmap() being to reduce
CPU consumption and buffer copies but the mmap() family of programming
interfaces is much richer than low-level read/write, pread/pwrite, or
stdio, because madvise() provides the ability for I/O scheduling, or
to flush stale data from memory. In recent Solaris, it also includes
provisions which allow applications to improve their performance on
NUMA systems.
