Wuffs/PNG can decode roughly 2.0x - 2.5x faster than libpng.

I'm closing this to clean up a little. libpng and stb_image were included in the benchmark as the "popular choice" libraries at the time. There's now other PNG implementations that should be even faster (eg. https://github.com/richgel999/fpng), but I'm not interested in maintaining a benchmark for any of them. |
