Gzip是若干种文件压缩程序的简称,通常指GNU计划的实现,此处的gzip代表GNU zip。 zh.wikipedia.org zh.wikipedia.org Gzip: gzip is a file format and a software application used for file compression and decompression. en.wikipedia.org en.wikipedia.org ...
But wait, since gzip decompression is inherently singlethreaded (aside from CRC calculation) how can it be more than 100% faster? Because pgzip due to its design also acts as a buffer. When using unbuffered gzip, you are also waiting for io when you are decompressing. If the gzip decoder...

Gzip as a Software Application Beyond the file format, gzip is also a software application used for file compression and decompression. Originating from the GNU Project, this open-source software helps minimize the size of files, directories, and filesystems. It combines the LZ77 algorithm and Hu...
