Go并行gzip压缩。它完全兼容gzip可直接替换 "compress/gzip"。它将待压缩内容拆分成多块然后并行压缩，对于大数据量压缩非常好用。

var b bytes.Buffer  w := gzip.NewWriter(&b)  w.SetConcurrency(100000, 10)  w.Write([]byte("hello, world\n"))  w.Close()

性能比较

Compression cost is usually about 0.2% with default settings with a block size of 250k.

Example with GOMAXPROC set to 4 (dual core with 2 hyperthreads)
