According to the HTTP RFC, a client must not maintain more than
2 open connections to the server. WebClient is respecting this
restriction.

You can raise the limit by addding this to your app.confg:

<configuration>
    <system.net>
       <connectionManagement>
          <add name = "*" maxconnection = "10" />
       </connectionManagement>
    </system.net>
</configuration>

or with

System.Net.ServicePointManager.DefaultConnectionLimit = 10;
