NATS pub-sub, publish rate affected by the number of subcribers

[kevinignas]

Hello I have a question about pubsub.

I was testing the pubsub rate with NodeJS and later I found the number of subscribers affect publish performance.

I wonder if it is actually how it is or if I miss anything in my testing? I also found the nats bench result when testing 1:N throughput test the publish rate is also lower than 1:1 here https://docs.nats.io/using-nats/nats-tools/nats_cli/natsbench#run-a-1-n-throughput-test.

Thanks in advance.
