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 support up to "version" 
4.1), the MSVC compiles were run through wine, as I don't think 
running in a virtual machine would give reproducible results. 
However, because of the use of Wine the MSVC results are not 
more than an indication.


For the GCC 4.8 results, there is a*very nice 60% to 70% speed 
increase* when encoding with preset -8 between FLAC 1.3.0 and 
current git.
