Beta release limitations

The new Site optimizer performance tools are in beta. In future releases, expect to see changes including new features and adjustments to metric definitions.

Here’s an overview of the prerequisites you need to meet to start using the new Site optimizer as well as a quick look around the overview screen.

Prerequisites

To use the new Site optimizer, you need:

  • Site admin permissions in Jira Cloud

  • Jira Premium or Enterprise plan

  • Enrollment in the Early Access Program via the Atlassian product team

Access Site optimizer

To access the new Site optimizer:

  1. In Jira, Select System from your global settings.

  2. Select Site optimizer from the menu on the left.

First look at the new overview screen

Performance factors

The overview screen is where you see the top factors that may be impacting your performance and scale. These help you understand potential actions you can take to improve performance and protect against degradations. The recommended actions are based on a combination of your own data as well as Atlassian’s own expertise working with thousands of Cloud customers.

Load times

Lower down on the overview screen, you will see four load time charts:

  1. Overall load time, aggregated across the three experiences

  2. Board load time

  3. Work item load time

  4. Backlog load time

These charts aggregate load time data from all end users across your site. You can view both median (50th percentile) and P75 (75th percentile) values, looking back up to 12 weeks in order to track changes over time.

Load time is measured using Time-To-Visually-Complete, or TTVC. TTVC measures the load time an end user experiences. Specifically, it captures the time until the visible content stabilizes and stops changing. Note that TTVC differs from backend or API response times, as it reflects the entire load time experienced by the user interface, not just the backend response.

Exploring the rest of Site optimizer

In addition to the Overview screen, there are three other tabs: User setup, Board performance, and Limits & cleanup.

User setup

The User setup screen provides insight into how your site’s load times are affected by the hardware, software, and network connection of your end users as they access Jira. Click here to learn more about User setup.

Board performance

The Board performance screen displays your site’s boards, identifies those with slow performance, and offers recommendations to optimize them. Click here to learn more about Board performance.

Limits & cleanup

The Limits & cleanup screen displays limits and guardrails for key Jira entities, as well as optimization tools to help clean up old data and streamline configurations. Click here to learn more about Limits & cleanup.
