Compression speed ~= Decompression speed. (around 200-300 MB/s)
CPU notes: LZZQ uses 32KB dictionary, reduce to 16KB (change HASH_SIZE to 4*1024) for good L1 cache access (with little reduction in ratio).

文件夹的压缩和解压缩功能测试程序
由于要用程序压缩一个文件夹,因此选用zlib库。
在zlib中的例子程序zpipe.c中,给出了如何压缩一个文件,这里稍加扩展,对一个文件夹进行压缩。
说来也简单,就是将文件夹/目录下的每个文件找到并压缩到一个文件中。
