I am facing issue of poor performance when used WCF having NetTcpbinding with Load Balancer
We have win form application which consumes WCF (net.tcp protocol). In production we have web Farm having 3 servers with load balancer (F5). WCF hosted in IIS. We are testing with only 1 user
Now when we point WCF to specific server (using either server name or IP); application really perform well. However when we give the DNS name (so that request is pass through load balancer) there is a significant drop in performance. Network team is saying from there side everything is properly working. Please help
Following is the configuration that i have tin WCF web.config file.
