Senior Service Engineer, Microsoft Visual Studio Team Foundation Service
Both a TFS Proxy server and a TFS Application Tier include a Version Control cache on disk. This allows each of the servers to service simple Download() requests without having to go to the Data Tier.
A “Cache Hit Rate” is represents as a percentage how many requests were able to be served from the cache, instead of going to the Data Tier (or in the case of the Proxy – to the Application Tier). A higher percentage is better.
If you have a TFS Proxy server, you can use TfsServerManager from the Team Foundation Power Tools to find out the Cache Hit Rate.
What I didn’t know is that you can also call a web service on the Application Tier server to get the same numbers. This is the same web service and instructions detailed on this MSDN page How to: Examine Cache Performance for Team Foundation Server Proxy – but use it on the AT.
You should get a response with the following attributes:
CurrentCacheSize NoOfRequests OverallCacheHits NoOfFilesInCache OverallCacheMisses CacheHitsPercentage="96.6" CacheMissPercentage="3.4" ServerId= ServerUrl=http://tfsserver:8080/
You could also write a utility that calls this webservice for you instead of logging on to the server directly.

I am doing some investigating on our install that was completed by a former IT employee. I noticied that when I look at Perfmon there are 2 server instances listed. One as the server name, the other as the IP address of the box. Any thoughts on why I would see both of these? Is there another configuration option out there for the proxy setup?
This would be because two people that have a proxy configured are connecting to the same TFS server using different addresses.
