performance icon Introduction

Performance testing looks at 2 elements: time to first byte and download speed.

A low score for time to first byte (response time) may indicate a performance issue with your Webserver, App or Database Servers.

If you have a low score for download speed the you should investigate your bandwidth utilisation.

Walkthrough of the Performance Category

Performance

The Performance testing provides a management overview of the Performance category showing the current score and 2 charts: 1. Response Time - the average time to first byte for recent audits and 2. Download Speed the average download speed for recent audits.

You can drill down into further details into both of these charts.

Response time - you can see the average time to first byte in milliseconds. The time to first byte is the server delay between Sitemorse requesting an object and the server starting to send it, averaged across all requests made during the audit. The ten slowest URLs are also listed, together with their respective time to first byte.

Download speed – you can see the actual average download speed in kB/s, which is the speed at which the server transmitted data to the Sitemorse system averaged across all requests during the audit. The ten slowest URLs are also listed, together with their transfer speeds.
