Xdelta Vs Bsdiff, Aug 30, 2023 · We chose the Google open-vcdiff and xDelta algorithms for testing since they are mature, use the more advanced block move approach, produce small size delta/patch files, and are not line-based but are straightforwardly applied to opaque binaries. HDiffPatch is better than bsdiff and can produce bsdiff format which is smaller than bsdiff in most cases. It turns out that rdiff uses a slightly better algorithm in terms of memory, but it creates a bigger patch (delta) file than either of bsdiff or xdelta3. For comparison between xdelta and bsdiff, the bsdiff (mbsdiff) seems to be more efficient in terms of delta size and memory consumption. Nov 6, 2025 · 本文深入探讨了三种主流差分算法：Xdelta3、bsdiff和Courgette，详细解析了各自的工作原理、应用场景和优劣对比。 Xdelta3适用于二进制文件，支持VCDIFF格式；bsdiff生成更小的二进制补丁；Courgette针对可执行文件，通过反汇编优化差分，特别适合大型软件更新。 This paper conducts the first systematic study to understand the performance of four widely used differencing algorithms for mobile application updates, including xdelta3, bsdiff, archive-patcher, and HDiffPatch with respect to five key metrics, including compression ratio, differencing time/memory overhead, and reconstruction time/memory overhead. Nov 30, 2025 · An interactive exploration of the bsdiff binary diff algorithm used for software updates in macOS and Chrome. .
