To whom it may concern: I did some benchmarking with the official xiph build of flac v1.3.2.CPU: i5-2400 @ 3.1 GHz SSD: Samsung 850 EVO 250 GB OS: Windows 8.1 64 bit Compression: -8 (the timing was done with "timer64.exe", v14 by Igor Pavlov)flac132_x86_xiph: Kernel Time = 2.078 = 2% User Time = 75.515 = 95% Process Time = 77.593 = 98% Virtual Memory = 14 MB Global Time = 78.839 = 100% Physical Memory = 14 MB 1.167.279.038 Bytes in 40 files flac132_x64_xiph: Kernel Time = 2.171 = 3% User Time = 65.437 = 95% Process Time = 67.609 = 98% Virtual Memory = 14 MB Global Time = 68.857 = 100% Physical Memory = 13 MB 1.167.279.038 Bytes in 40 files flac131_x64_xiph: Kernel Time = 2.203 = 3% User Time = 67.515 = 95% Process Time = 69.718 = 98% Virtual Memory = 14 MB Global Time = 70.808 = 100% Physical Memory = 13 MB 1.167.334.662 Bytes in 40 files flac131_x64_icl: Kernel Time = 2.187 = 3% User Time = 68.156 = 95% Process Time = 70.343 = 98% Virtual Memory = 14 MB Global Time = 71.690 = 100% Physical Memory = 13 MB 1.167.334.662 Bytes in 40 files flac131_x64-git-bc1f15db (AiZ): Kernel Time = 2.281 = 3% User Time = 67.171 = 95% Process Time = 69.453 = 98% Virtual Memory = 14 MB Global Time = 70.667 = 100% Physical Memory = 13 MB 1.167.279.038 Bytes in 40 files Bottom line: In my test, although performed on an ancient CPU, Xiph's 64 bit build was the fastest encoder. And additionally saved some bytes . 32 bit binary is significantly slower. I've added tests of different other flac 1.3.1 binaries (collected in this thread). N.B. AiZ's binary was the fastest on my Core2 CPU... Big thanks to the team (Eric, lvqcl, et al.) .sundance.
