I dunno what Unix bench is... but isn't 153.6/208.6 close to 600/800
in terms of a fraction?

It isn't really fair to compare different machine configurations with
different OS's, and declare that the OS is the only factor involved.

Make Host3 or Host4 have both versions of the linux kernel in /boot
and try each on the same machine.
