Understanding the URI Performance Information

The performance information for each URI and each of the three distribution diagrams is the same. The details of each element is as follows:

Element	Meaning
Transaction count	Total number of transactions that have been processed for the section.
First transaction	The time spent in the very first transaction for this URI or the very first transaction in the case of all URIs (*). This first transaction is always isolated as startup time for some underlying services may cause delays that are not consistent beyond the first transaction and can therefore result in misleading data on small stress testing runs.
Lowest recorded	The lowest transaction time recorded for the selected URI
Max recorded after first	The highest transaction time recorded for the selected URI, excluding the first transaction. Please note that for the combined URIs (*) this is only excluding the very first transaction for any given URI. Hence it can be the second largest first transaction for a secondary URI.
Average	This is the average response time for the selected URI, including the first transaction.
Average without first	This is the average response time, excluding the first transaction. For small stress test runs, this is a more accurate reflection of the real end user experience.

The distribution diagrams show transactions below 100ms, below 1s and up to 20s. Transactions taking 20 seconds or more will all be included in the >=19 seconds group. These distribution diagrams are especially useful when combined with the transaction counts in the rule sets.
