FSR
The loader reads the open lots and their prices from the room, so the lots above were rendered by the server. The scoreboard and recent sales come from the same read.
Plaza
One room settles every bid in order: it checks the raise and your purse, holds your money while you lead, returns it when you are outbid and answers each bid by the number the page gave it.
Fibre
Bids reach the room through its Fibre command queue, so two bids in the same instant are settled one after the other, never at once.
