To clarify: my tests were 'make buildworlds'. The first number was while building running a EV5 optimised world to do so, the second used the EV6 world. I have not tried to build an EV5 buildworld using the EV6 world (so in other words an empty /etc/make.conf). The machine is currently churning on RC3 for re@ so I cannot go try it. > One should also consider that compiling binaries with more optimization > usually takes additional cycles too.
