It is pretty well known optimizing for the original pentium causes slow
downs on newer chips, like p2/p4/athlon, however the bug is in the
design of the original pentium itself not anything in the software
optimization. Also using O3 over O2 will usually causes slower running
programs due to code bloat wrt cpu cache.
