The lightening fast trades in binance and bitmex look amazing. What technology makes them so super fast.
Bitmex is awful and almost always overloaded on high trades. Binance doesn't have those problems.
It's matter of software and nothing else because all trades are off-chain. If you are looking for blazing fast futures, you should try Deribit. They doesn;t have the Bitmex overload problem eve during high load.
