I am surprised how good Sun's technical marketing was for you to think
this.  Linux has scaled better since the early 2000s.  The Solaris
x86-64 port has some real gaffes in it to this day at least as visible
in the OpenSolaris derivative codebases, serialization in the locking
primitives kind of things.
