ZXC reports roughly 2× faster decoding than LZ4 at similar compression ratios

libzxc.org 10 min read Editor score 7/10

ZXC's published comparisons show about 2× LZ4's decode speed at similar or smaller output sizes, including on Apple M2 and AMD processors. Engineers weighing compression for read-heavy workloads can use the results to identify a candidate for further testing.

What

ZXC is a C lossless compression library designed for data compressed once and decompressed many times.

How

Its encoder spends extra time on parsing and statistics so a short, low-branch decoder can use modern processor pipelines and SIMD.

Why it matters

For shipped assets such as firmware, faster decoding and equal-or-smaller output can reduce device load time and data size.
