| Issue | Action | Related task |
|-|-|-|
| Your instance is slow | Decrease the scale factor | [Adjust the scale factor for Event Framework jobs](https://servicenow-prod.fluidtopics.net/unBVi4qnJnHcsqQpR1~IIA "Adjust the scale factor to modify the number of worker threads per app node, which increases or decreases throughput.") |
| Discovery is slow | Increase the scale factor | [Adjust the scale factor for Event Framework jobs](https://servicenow-prod.fluidtopics.net/unBVi4qnJnHcsqQpR1~IIA "Adjust the scale factor to modify the number of worker threads per app node, which increases or decreases throughput.") |
| Discovery is slow when both Cloud and IP Discovery are running | Use a single queue for both Cloud and IP-based events | [Configure a single queue for Cloud-based and IP-based events](https://servicenow-prod.fluidtopics.net/zQgiwAomIDDRoLZISxlHCg "Configure Cloud-based and IP-based events to share a single queue, which helps reduce the impact of Discovery on app nodes.") |
| Discovery is preempting other work | Reduce the worker priority of the background job | [Configure background worker job priority for Event Framework](https://servicenow-prod.fluidtopics.net/_RUni84J~Qt91EcLdGh55Q "Configure the job priority of background workers to help prevent noncritical tasks from preempting important work, which promotes system efficiency and stability.") |
| Nodes are executing too many Discovery jobs simultaneously | Configure event processors to execute on specific nodes | [Configure event processors to execute on specific nodes](https://servicenow-prod.fluidtopics.net/Fyiy8qSQXOVRXlrh58QcJQ "Configure the discovery.event.pin.jobs system property to enable event processors to execute on specific nodes and distribute the work evenly. The scale factor calculates the number of nodes but doesn't pin jobs to specific nodes.") |
