I am looking into Performance issues of an Asp.Net 2.0 Web Site which uses a WCF service. On the Web and the WCF Host Service I am adding some Perf Counters to analyse the application behaviour. What are the Performance Counters which will be useful. I have created a partial list. Can someone suggest me if I am missing any important counter.
