Transaction Time

Transaction time, which is the delay taken for an HTTP or HTTPS operation to complete, aggregates send time, processing time, and response time figures.

You must plan for factors that can affect transaction time. These include:

• Network speed and latency. You need to examine latency over a Wide Area Network (WAN). Latency can significantly increase retrieval times for large amounts of data.

• The complexity of the Portal Desktop.

• The browser’s connection speed.

  For example, a response time delay is longer with a connection speed of 33.6 kilobytes per second than with a LAN connection speed. However, processing time should remain constant. Transaction time through a dial-up connection should be faster than transaction time displayed by a load generation tool because it performs data compression.

When you calculate transaction time, size your Portal Server so that processing time under regular or peak load conditions does not exceed your performance requirement threshold and so that you can sustain processing time over time.
