In my server many requests need to handle a loop to unmarshal json strings and I find gc is very frequency

If you can't avoid generating garbage, then at least try to reuse it!
That's what sync.Pool is for (don't make the map, reuse one).

Can't you read the Redis reply by chunks?

Try https://github.com/pquerna/ffjson to improve speed and reduce garbage generation. This in combination with sync.Pool will increase your throughput by A LOT.

Also try out http://ugorji.net/blog/go-codec-primer - depending on your usage that is also really great.
