| # Benchmarks |
| |
| `wuffs bench -mimic` summarized throughput numbers for various codecs are |
| below. Higher is better. |
| |
| "Mimic" tests check that Wuffs' output mimics (i.e. exactly matches) other |
| libraries' output. "Mimic" benchmarks give the numbers for those other |
| libraries, as shipped with Debian. These were measured on a Debian Bullseye |
| system as of September 2022, which meant these compiler versions: |
| |
| - clang/llvm 11.0.1 |
| - gcc 10.2.1 |
| |
| and these popular "mimic" library versions, all written in C: |
| |
| - libbz2 1.0.8 |
| - libgif 5.1.9 |
| - libpng 1.6.37 |
| - zlib 1.2.11 (we'll call this "ztl" or "zlib the library", as opposed to "zlib |
| the format") |
| |
| and these alternative "mimic" library versions, again all written in C: |
| |
| - [libdeflate](https://github.com/ebiggers/libdeflate) 1.7.1 |
| - [libspng](https://github.com/randy408/libspng) 0.7.3 |
| - [lodepng](https://github.com/lvandeve/lodepng) 20220717 |
| - [miniz](https://github.com/richgel999/miniz) 2.2.0 |
| - [stb](https://github.com/nothings/stb) 2.27 |
| |
| Unless otherwise stated, the numbers below were taken as of Wuffs git commit |
| 315b2e52 "wuffs gen -version=0.3.0-rc.1", the first Wuffs v0.3 release |
| candidate. As for the CPU model: |
| |
| $ cat /proc/cpuinfo | grep model.name | uniq |
| model name: Intel(R) Core(TM) i5-10210U CPU @ 1.60GHz |
| |
| |
| ## Reproducing |
| |
| The benchmark programs aim to be runnable "out of the box" without any |
| configuration or installation. For example, to run the `std/zlib` benchmarks: |
| |
| git clone https://github.com/google/wuffs.git |
| cd wuffs |
| gcc -O3 test/c/std/zlib.c |
| ./a.out -bench |
| rm a.out |
| |
| A comment near the top of that `.c` file says how to run the mimic benchmarks. |
| |
| The output of those benchmark programs is compatible with the |
| [benchstat](https://godoc.org/golang.org/x/perf/cmd/benchstat) tool. For |
| example, that tool can calculate confidence intervals based on multiple |
| benchmark runs, or calculate p-values when comparing numbers before and after a |
| code change. To install it, first install Go, then run `go install |
| golang.org/x/perf/cmd/benchstat`. |
| |
| |
| ## wuffs bench |
| |
| As mentioned above, individual benchmark programs can be run manually. However, |
| the canonical way to run the benchmarks (across multiple compilers and multiple |
| packages like GIF and PNG) for Wuffs' standard library is to use the `wuffs` |
| command line tool, as it will also re-generate (transpile) the C code whenever |
| you edit the `std/*/*.wuffs` code. Running `go install -v |
| github.com/google/wuffs/cmd/...` will install the Wuffs tools. After that, you |
| can say |
| |
| wuffs bench |
| |
| or |
| |
| wuffs bench -mimic std/deflate |
| |
| or |
| |
| wuffs bench -ccompilers=gcc -reps=3 -focus=wuffs_gif_decode_20k std/gif |
| |
| |
| ## Clang versus GCC |
| |
| On some of the benchmarks below, clang performs noticeably worse (e.g. 1.3x |
| slower) than gcc, on the same C code. A relatively simple reproduction was |
| filed as [LLVM bug 35567](https://bugs.llvm.org/show_bug.cgi?id=35567). |
| |
| |
| ## CPU Scaling |
| |
| CPU power management can inject noise in benchmark times. On a Linux system, |
| power management can be controlled with: |
| |
| # Query. |
| cpupower --cpu all frequency-info --policy |
| # Turn on. |
| sudo cpupower frequency-set --governor powersave |
| # Turn off. |
| sudo cpupower frequency-set --governor performance |

| # GIF |
| |
| The `1k`, `10k`, etc. numbers are approximately how many pixels there are in |
| the decoded image. For example, the `test/data/harvesters.*` images are 1165 × |
| 859, approximately 1000k pixels. |
| |
| The `bgra` vs `indexed` suffixes are whether to decode to 4 bytes (BGRA or |
| RGBA) or 1 byte (a palette index) per pixel, even if the underlying file format |
| gives 1 byte per pixel. |
| |
| The `full_init` vs `part_init` suffixes are whether |
| [`WUFFS_INITIALIZE__LEAVE_INTERNAL_BUFFERS_UNINITIALIZED`](/doc/note/initialization.md#partial-zero-initialization) |
| is unset or set. |
| |
| The libgif library doesn't export any API for decode-to-BGRA or decode-to-RGBA, |
| so there are no mimic numbers to compare to for the `bgra` suffix. |
