Common Lisp is a standard.  Different implementations
of it should respect the standard, but the standard
allows for different behaviors to some extent, esp.
wrt performance.  CL has multiple ways of declaring
different levels of optimization, which a given
implementation can support or not.

Particular optimizations are not expected to be
portable.
