Question about RPC and Compression

Question

I’m prototyping a multiplayer game at the moment where the map can be altered by the players. This means I need to send the current state of the map to new players when they join. I’m currently compressing the buffer before sending it as a RPC to the client. I was wondering if RPC calls already compress the parameter data and whether I’m wasting time compression data that will already be compressed?
