TCP vs Websocket performance and bandwith usage

[zerodwide]

Feature Proposed
Comparison between TCP & Websocket in performance and bandwidth usage

Use Case
i used rathole for a middle tunnel for v2ray vpn service for a short period of time.
my problem is bandwidth usage is not 1:1 for sending and receiving. sending is about 20% more than receive!
as i am paying for bandwidth this is really my concern.

i am using gost ssh for tunneling, and usage is 1:1

so i was wondering is any enhancement i can do to bring usage close to 1:1 ?
what if i use websocket?
does it use less traffic?

thanks in advance.

Infact ,using websocket may take more bandwidth
