Go并行gzip壓縮。它完全兼容gzip可直接替換 "compress/gzip"。它將待壓縮內容拆分成多塊然后并行壓縮，對于大數據量壓縮非常好用。

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

性能比較

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)
