@donmccurdy I did some benchmarks and this is 80% as fast as the zstddec package but 1/5 the size. Zstdify is 7.67 KiB bundled/compressed while zstddec is 40.66 KiB.

@BenHouston3D @donmccurdy The claims *really* did not add up for me - zstd does not decompress this quickly, unless your data is just not compressible at all! - so I tried this, and on a non-zstd UASTC ktx2 file I'm getting ~100 MB/s decode performance. Native zstd decompresses at 1.7 GB/s. zstddec is about 1 GB/s. Your binary benchmarks are not using compressible data.
