samba is designed to be portable to many different OSes. One design choice made to
reach that goal is to be single-threaded.

The illumos kernel is highly threaded. SMB, NFS, and SCSI services in-kernel are also
highly threaded and efficient.

Different design goals --> different optimization points. For some workloads it makes a
big difference.
