As a good real-world benchmark, I propose you to try bzip2.
It is a quite small program, easy to recompile. At runtime, it is
notoriously slow on any machine. You can try to compress a file of some
size, let's say 1 MB, and see how much time it takes. You should try
with a file big enough no not be annoyed by the speed of disk access.
Then you can rebuild bzip2 with the different CPU options, and see the
timing differences.
