# Limits and scaling

> How many agents and task queues a tenant may have, what a large plugin and a tenant of many small plugins cost, what 10,000 agents in one tenant measured, and what a fleet of nodes under load measured.

For: cluster operators and plugin authors.

Plan capacity from the tenant limits, the queues your plugins need and the measurements for your deployment. Agent counts alone do not describe the work a node or Temporal backend must handle.

A tenant's agents run on Temporal task queues, and every queue a node polls is registered in the tenant's Worker Deployment version when a new runtime version first polls it ([Temporal](https://docs.oz0.ai/concepts/temporal)). That registration is what limits how many queues a tenant may have, so Orchestrator Zero keeps the queues few: a plugin's agents and flows share one queue for each set of node labels they require ([routing](https://docs.oz0.ai/concepts/routing)).

Check [Compatibility](https://docs.oz0.ai/reference/compatibility) for platform requirements and integration maturity, and [Known issues](https://docs.oz0.ai/reference/known-issues) for operational problems and workarounds.
