I have observed that the USD-M futures websocket api (* wss://ws-fapi.binance.com/ws-fapi/v1) has very high latency in comparison to spot websocket api ( wss://ws-api.binance.com:443/ws-api/v3*).
RTT for USD-M futures is around 6 milliseconds while for the spot api is around 1.6 milliseconds. Why?
I have seen that this is is consistent no only in the futures websocket API vs spot websocket API but also in the futures websocket streams vs spot websocket streams.
Is there any way to fix this.
