WCF NamedPipeBinding for DB Server

10/20/2014 08:33 Xio.#1
I've implemented a Database Server which basically handles all the IO from the Game and Login server.

If I run it in debug mode I get 1100 ops per second max, on release build I get 2600 ops per second max per channel.

I can spawn 1.5 channels per cpu core until the performance does not increase anymore. So I'm having 12 channels and 32k ops per second on the release build.

Is there a way to further improve the ops?


PHP Code:
public static void CreateDataExchangeInstance()
        {
            var DataExchangePipe = new NetNamedPipeBinding { ReceiveTimeout = TimeSpan.MaxValue };
            DataExchangeHost = new ServiceHost(typeof(DataExchange), new Uri("net.pipe://localhost"));
            DataExchangeHost.AddServiceEndpoint(typeof(Interfaces.IDataExchange), DataExchangePipe, "DataExchange");
            DataExchangeHost.Faulted += DataExchangeHostFaulted;
            DataExchangeHost.Closed += DataExchangeHostClosed;
            DataExchangeHost.Open();
        } 

for each player, I can get a maximum of 21 ops per second.

Not with this method. These pipes use memory mapped files under the hoods and they are the fastest way for two processes to communicate in WCF. I`d still consider using a socket based approach instead of pipes though, but that depends solely on your circumstances and setup.
