Google开源了压缩算法Zopfli，它压缩后的文档容量更小，但代价是需要更多的CPU时间，比较适合于特定应用。Google称，在最大压缩率下Zopfli输出的文件比zlib小3%到8%，认为Zopfli代表着目前最先进的Deflate兼容压缩算法，它采用C语言编写，便于移植。但Zopfli的缺陷是需要的CPU处理时间比 zlib高出2到3个数据级，因此比较适合一次压缩多次传输的应用，如Web静态内容。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
