Not sure, I didn't set CFLAGS which seems to result in using both: -O3 -funroll-loops -Wall -W -Winline -g -O2 I think funroll-loops can be harmful, the Fedora package is compiled with -O2 and funroll-loops is used only for the stream_encoder file and it seems decoding is a tiny bit faster than with the git version. Unfortunately I don't recall the details.
