Dual Socket

Each node participating in the cluster can establish two dual sockets connections with every other node. The purpose of increasing the number of connections is to increase throughput by maximizing network usage. As network I/O is a slow process, opening multiple connections will help improve the performance.

Configuring Dual Sockets

By default, dual connections are disabled. You can enable or disable this feature by specifying the following options in the <appSettings>of the NCache service's config file.

<appSettings>

  <add key="NCache.EnableDualSocket" value="true"/>

</appSettings>

Note

If you are using cache as InProc, you need to specify this in the config.exe file of your application.
