The slower is probably due to the unroll loops switch which can actually hurt code due to the larger footprint (less cache coherency).
The cache issues are so important with current processors that I'd suggest throwing -Os (optimize for size) into the mix people test. That one may stack usefully with -O2, but probably not with -O3 (3 includes optimizations that increase code size).
