Describe the issue/error/question

Sometimes when running this flow it will run in 1 second and other times it will take 20 seconds. This is running on a t3.medium server in AWS.

What is the error message (if any)?

No error message - it just takes a long time.

Please share the workflow

Hi @cgsmith,
different response times can happen for different reasons so it’s hard to say what is happening here. A couple of things to investigate could be

  • Are you doing any 3rd party requests in your subworkflow that could take a long time?
  • Is your system under heavy workload processing other workflow executions while it’s happening?
  • Did you try using execution mode main to see if that makes a difference?
