Network Trace:

• SPIisLatency. This is a measure of the amount of time (in milliseconds) that the request spent queued and waiting to be processed by IIS (Internet Information Services – the web server). Ideally, it should be zero or very close to zero. In my example, the SPIisLatency is 3ms.
• SPRequestDuration. This is the amount of time (again, in milliseconds) that it took to process the request on the server. Basically, this is the end-to-end processing time for the page. Healthy pages range from a couple hundred milliseconds to around a second depending on the content of the page. In my example, the SPRequestDuration is 249ms.
• X-SharePointHealthScore. This is the value, from zero to ten, that indicates how heavily loaded the SharePoint Server is at the time when the page was served. A score of zero means the server is not under load, while a score of ten means the server is overloaded. As the X-SharePointHealthScore goes up, the server begins to selectively suspend work designated as “low priority,” like some Timer Service jobs, Search requests, and various other low-priority tasks. ideally, this value should be zero – or close to it. In my example, the value is zero. For example see here
