Awesome! Thanks M
For anyone wondering, here's a PDF comparing encoding speed,
decoding speed and compression between FLAC 1.2.1, 1.3.0 and
1.3.1pre1.
Compiles on a Intel Core 2 Duo T9600 (SSE up to and including
4.1, no AVX), Kubuntu 14.04.1, GCC 4.9.1.

Currently FLAc defaults to -msse2 which means that SSSE3 and SSE4.1
optimizations don't work with GCC < 4.9. SSE4.1 is useful
Hi all,
I thought it was a good idea to get an overview of the
developments since the release of 1.3.0, so here are a few graphs.
The first was compiled with GCC 4.8, the second was compiled
with MSVC 2013. Both were tested on a Kubuntu 14.04 machine,
with an Intel Core 2 Duo T9600 (SSE supp
Hi all,
I once more did a performance check on the latest git. The
binaries in this new test have been compiled with GCC 4.8.1 on
Ubuntu 13.10. The CPU is a Intel Core 2 Duo T9600.

Hi all,
I had some time to spare so I made a comparison of current git versus
the FLAC 1.3.0 release considering encoding and decoding speed. This was
done with GCC 4.7.3 for AMD64 linux.
There's a very nice speedup visible. Keep up the good work!

That depends on the way you define speed. For decoding this doesn't seem
to be true. I rer

In that case I hope you saw the previous one, because the decoding
speed-up was credited to be one of your patches, according to some
people over at HydrogenAudio:

I'm always interested in performance tests :)
Hi all,
I was doing some checks in preparation of updating the comparison on the
FLAC page this summer and I thought the results might be interesting for
people on the dev list as well.
Because the mentioned comparison runs a few codecs through wine I wanted
to check whether wine gives a per
