Linux optisa command

On the Solaris operating system, the optisa command determines which variant instruction set is optimal to use on the system. The optisa command prints which instruction_set out of the ones specified in the command performs best on this machine. In this case, "best" is defined by the order where instruction set names are returned by isalist.
