Meanwhile, may I humbly suggest pgzip.

There's also http://godoc.org/golang.org/x/build/pargzip which we wrote for Go's build system.

@bradfitz - Very nice. I see you concatenate complete gzip archives. I use the flate.NewWriterDict in the builtin library to avoid the compression loss. While we are at it, there is also bgzf, which makes seeking inside a compressed file possible via a small addition to the gzip format.

Either way, I don't see any reason for this feature to be in the standard library. For the most common use-case (webservers), you get non benefit from parallel compression.

I agree. At this point this seems unlikely to be added in the standard library, so I think it's okay to close this issue.
