Does Jira Align standardize portfolio hierarchy refresh timing across large value streams?

Portfolio hierarchy refresh behavior in Jira Align

Jira Align surfaces real-time portfolio hierarchy roll-ups across value streams, but the refresh interval and scaling behavior for tenants running many concurrent value streams is not explicitly standardized in available documentation. The goal is to determine whether roll-up timing is fixed by the platform, varies by contract tier or release, or can be adjusted per tenant.

Because Jira Align is a SaaS product, UI and feature availability may differ across contract tiers and release cycles, so observed behavior should be treated as release-specific rather than universal.

Is the portfolio hierarchy refresh interval standardized across all Jira Align tenants, or does it scale with value-stream volume? Which contract tiers or releases expose configuration for roll-up timing? What practical limits apply before refresh behavior degrades for large hierarchies?
