Sorry for skipping that info. I did the tests a few months
ago and the compiler version was 3.2-4. I did compile
with SSE. It said there was SSE support (not for AMD explicitly).
Was I wrong? Is 3.3 actually out? When did it come
Sorry to misinform people as the version 3.3 may provide more
performance over the one I tested.
