Deployment process page is slow to load when project has many steps using the same step template

[HuyPhanNguyen]

Severity

Reproducible on self-hosted 2025.4.10294. Confirmed on latest cloud instance

Version

Latest Version

I could reproduce the problem in the latest build

What happened?

Multiple pages are slow to load when a project has 100+ steps referencing the same step template (e.g. "Deploy Child Octopus Deploy Project" community template in an orchestrator project).

Measured on a local reproduction with 105 steps (each with an ~86KB script from a step template):

Page	API Call	Time	Size	Count
Project page	useronboarding/{projectName}	~21s	2.9kB	x2
Project page	projects/{id}/summary	~19s	1.6kB	x1
Process list page	deploymentprocesses	~24s	706kB	x2
Process editor page	deploymentprocesses	~18s	706kB	x1
Process editor page	variables	~18s	5.7kB	x1

Reproduction

1. Create a step template with a large script (~86KB), or use the "Deploy Child Octopus Deploy Project" community step template
2. Create a project with 100+ steps all using that step template
3. Navigate to the project page and observe load time
4. Navigate to the deployment process page and observe load time
5. Click into a step to open the editor and observe load time

Error and Stacktrace

No error. Performance issue only.

More Information

No response

Workaround

No practical workaround. The script duplication comes from step template usage which cannot be avoided when using community step templates like "Deploy Child Octopus Deploy Project" in orchestrator projects.
