Do you have Linux compatibility installed on the FreeBSD machine?
You should then be able to run the Linux binary to see what happens then.
I have had once the problem of a task moving from CPU to CPU and s
performing badly on FreeBSD.
I am not informed how this is handled currently.
I also assume that this example is a single-threaded program which
should perform just fine on single CPU machine.
One other thing, can you just boot up with one CPU and one core to see
what happens then?
