Performance tests
...with the brand new laptop my employer gave me, which is why it runs Windows. There is no change between current git and 1.3.1, so I did a check with AVX disabled to check whether AVX is still faster (I suppose some SSE routines have been sped up?) and it indeed is. Results are here: http://www.audiograaf.nl/misc_stuff/Comparison on 64-bit Windows (2014 Intel, AVX2).pdf

Performance tests
Hi, Once again, I did some performance testing. Results are here: http://www.audiograaf.nl/misc_stuff/Comparison on 32-bit ARM (Raspberry Pi B).pdf http://www.audiograaf.nl/misc_stuff/Comparison on 64-bit Linux (2008 Intel).pdf I'll add some results for 64-bit Windows (2014 Intel with AVX2) in a few days. Results look nice, a 20% speedup on my x86_64 platform for the slowest...

Performance checks
...th 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. http://www.audiograaf.nl/misc_stuff/FLAC-performance-test-Linux-GCC-4.8.pdf http://www.audiograaf.nl/misc_stuff/FLAC-performance-test-Wine-MSVC-2013.pdf 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. -------------- next part...
