Performance and Scale Digest: 2025 Q3

[#1]

Hello Atlassian Community!

Welcome to the latest edition of the performance and scale digest, your go-to source for the latest performance, scale, and reliability updates across the Atlassian Cloud infrastructure. This quarter, we’ve released and announced many improvements that unlock faster performance, support for more users, and new ways to efficiently manage and clean up your environments. Let’s dive in!

Enterprise-grade scalability

Built to support organizations of any size, we’re committed to supporting more users across our apps so you can bring more teams together on a unified platform.

Announcing support for 50,000 agents on a single Jira Service Management site

Coming in Q1 2026, Jira Service Management Cloud will support up to 50,000 agents on a single site for Standard, Premium, and Enterprise plans. This vertical scaling milestone enables even the largest organizations to unify IT, support, and business teams within one centralized ITSM platform. When paired with Jira’s recent increase to 100,000 users on a single site, enterprises can scale both service management and software development side-by-side to accelerate delivery and impact.

Announcing support for 250,000 users on a single Confluence site

We aren’t stopping there! Building on last year’s jump to 150,000 users, Confluence Cloud will support up to 250,000 users on a single site later in 2026. As your organization grows, Confluence can serve as a company-wide intranet for critical announcements and knowledge, or as the hub where technical and non-technical teams collaborate to accelerate outcomes. Together, the combined boost in user capacity across Jira, Confluence, and Jira Service Management enables enterprises to bring more teams together on one teamwork platform to run their most critical work.

Performance improvements

Enjoy faster workflows and enhanced efficiency across your teams with these new updates.

New limits and guardrails for the Jira Cloud family of apps

New limits and guardrails have been announced for Jira, Jira Service Management, and Jira Product Discovery to help you manage your data shape and environment for a faster, smoother user experience as your organization grows. Starting February 2026, limits for certain data types will be enforced to help prevent performance issues, and guardrails are already available to provide recommended thresholds for keeping your sites healthy.

Type	Entity	Limit or Guardrail value
Limit (enforced starting Feb. 2026)	Fields per space	700
Limit (enforced starting Feb. 2026)	Work types per space	150
Guardrail (best practice; not enforced)	Work items per site	18,000,000
Guardrail (best practice; not enforced)	Spaces per site	8,400

New data management tools for the Jira Cloud family of apps

Announced alongside the new limits and guardrails, new cleanup tools make it easy for admins to remove unused fields and work types, helping to reduce clutter and boost performance across Jira, Jira Service Management, and Jira Product Discovery. Now available on all plans, these tools complement Site Optimizer by enabling every customer to quickly find and easily manage unused or outdated data:

• Optimize field configuration schemes

• Optimize work types in a work type scheme

Site Optimizer is now available for Jira Premium plans!

Site Optimizer is now available for Jira Cloud Enterprise and Premium customers, giving admins powerful insights into site health and easy tools to clean up unused spaces, work items, fields, and permissions. With these actionable insights, you can keep your Jira sites stable and high performing as your organization grows.

List and All Work views are combined into a single view in Jira

We’ve merged the List and All Work views in Jira into one unified experience for managing work items, simply called ‘List’. By combining the best principles from both views, it’s now easier for you to track work across all space types, with faster access to grouping, inline editing, hierarchy support, and more.

Enhanced Bulk Move API in Jira

The enhanced Bulk Move API enables teams to move multiple work items across different work types and spaces in a single request, reducing API calls and simplifying operations.

Previously, the API supported only simple, one-type-to-one-type moves. With this update, you can:

• Move work items of different work types from multiple spaces into a single target

• Assign standard work items to epics during the move

• Preserve hierarchy in the process

Major performance boosts for large Jira Cloud sites

We’ve rolled out significant performance enhancements for our largest Jira Cloud customers (20,000+ users), delivering noticeably faster load times across key experiences. These gains come from deep architectural upgrades—including database optimizations, smarter caching, and modular field configuration—driven by a multi-quarter initiative from the Jira Scale team.

Large-scale Jira customers are seeing the biggest performance improvements in:

• Backlog: up to 28.9% faster

• Work items: up to 24.0% faster

• Plans: up to 20.6% faster

Performance improvements to large Confluence environments

Doubling down on performance improvements, our largest Confluence Cloud customers (especially those working on large pages or complex tables) will now experience faster, smoother page loads! We’ve updated how we render tables to reduce layout shifts – helping pages load more predictably and perform better across the board.

These updates are already delivering impact across high-traffic Confluence experiences:

• View page: initial loads are up to 15% faster, with the slowest 1% of loads improving by up to 28%

• Space overview: initial loads are up to 8% faster, with the slowest 1% improving by up to 38%
