Wouldn't compression between redis and hiredis make sense as well?

How much load would compression put on a Redis instance that talks to n clients where each client sends/receives medium sized JSON docs. And how much would be gained in terms of faster responses from Redis.

Something like lzf or snappy maybe?

In my experience, snappy with very small messages (< 200 bytes or so) can increase bandwidth usage, so I'd say the way in which one uses redis can impact if compression is useful or not.
