Performance Test Report

Overview

The table lists the requests with the slowest overall runtime matching the following criteria (as configured in the reportgenerator.properties):

• Request runtime must be between 3,000 ms and 600,000 ms to be listed.
• A maximum of 20 requests per request name are listed.
• A total maximum of 500 requests are listed.

Each row in the table displays the data for one individual request. The request names are derived from the action names and may have been modified using request filter and transformation rules. When hovering over the request name, a pop-up will show further request information if available (e.g. the URL, HTTP method, or form data).

Baseline

The Baseline columns show the mean and p95 runtimes across all requests with the respective name to allow easy comparison with the runtime of the respective slow requests. These are the same mean and p95 values displayed in the Requests section.

Bandwidth

The Bandwidth columns show the incoming and outgoing bandwidth per request. XLT measures on socket level. Thus, actual incoming and outgoing data is recorded. XLT does not analyze or modify that data when taking the measurements.

The Bytes Sent column comprises all data sent out of the application including overhead such as HTTP(S) headers and SSL protocol data. The Bytes Received column includes all received data and the connected overhead. As the data is measured right above the socket level and before it gets decoded by the application, any compressed traffic is measured as seen by the network layer. The data size you see is not the expanded data as seen by the DOM parser.

Network Timing

The Network Timing columns display all low-level network timing data that has been measured on socket level. The following measurement points are shown:

• Connect Time: Time needed to establish a connection to the other system. Note that when you use keep-alive semantics during testing, the connect time will mainly be 0 except for the first request of a transaction.
• Send Time: Time needed to send the request to the other system. Depending on the payload and the network speed, this data often amounts to zero or very small values.
• Server Busy Time: Time spent waiting from sending the last bytes to receiving the first bytes.
• Receive Time: Time spent receiving data from the first to the last bytes received.
• Time to First Bytes: Total time from the connection start until the first bytes are received. Includes Connect, Send, Server Busy, and Receive Time.
• Time to Last Bytes: Total time from the connection start until the last bytes are received. This is the time needed to connect, send, and receive data. Often it is called network runtime. In contrast, the request runtime includes the network runtime and the application time needed to process header and protocol information and transfer the data from socket level to the application level.

Request Details

The Request Details columns show the HTTP response code and the start date and time of the request.

IP Addresses

The IP Addresses columns show the IP address used to perform the request, as well as all IP addresses reported by the DNS (if the information is available). If more than one address was reported, hover over the field to see a list of all the IP addresses.
