basic/stupid question, but need some explaining regarding the BroadcastingEchoServer.cpp code?

[M-U-X]

for (int i = 0; i < 32; i++) { std::string topic = std::to_string((uintptr_t)ws) + "-" + std::to_string(i); perSocketData->topics.push_back(topic); ws->subscribe(topic); }

wouldn't a single topic suffice? what's the need for 32?

        `.message = [&app](auto *ws, std::string_view message, uWS::OpCode opCode) {
        PerSocketData *perSocketData = (PerSocketData *) ws->getUserData();

        app->publish(perSocketData->topics[(size_t)(++perSocketData->nr % 32)], message, opCode);
        ws->publish(perSocketData->topics[(size_t)(++perSocketData->nr % 32)], message, opCode);
    },`

why are there two publish methods being called? wouldn't the first one the app->publish publish to all clients?

I may be misunderstand, but if I'm understanding this correctly this is a server that gets a message from a user then broadcasts to all connected users no?

This example probably served as a benchmark. So it spams messages like this

[M-U-X]

what about the two different publish calls, the second one is unnecessary? or does it serve a specific purpose?
