I think it would be a good idea to have some kind of "speedbump" tool that makes your software slower, but in a way where optimizing it would also optimize the faster version.

I don't know whether this is technically feasible, maybe you could run it on CPUs with good power management and force them to underclock or something.

You could use Qemu to emulate an older CPU, you would need to disable kvm with -no-kvm. There's also a throttle option I found while googling this.
