Sending less bytes over the wire - LZ4 compression of response body.
I tested lz4 on a simple React project and found that compression significantly reduces the message size.

I chose LZ4 because it focuses on compression and decompression speed than compression ratio. And it works very well on repetitive data (in our case, msgpack encoded 1s and 0s).
On the client side:
raw response -> msgpack encode -> lz4 compress -> tunnel
On the server side:
tunnel -> lz4 decompress - > msgpack decode -> raw response
