How tasks are processed

The task queue: what happens after you click "Start"

  • Once started, a task goes into your personal queue and gets the "Queued" status, then "Running".
  • How many of an account's tasks run at the same time depends on the section. "Link check" and "Site DR" tasks are processed several at a time and share one common pool of slots; "Domain history" has a pool of its own; "Domain selection" tasks always run strictly one at a time — the next one starts only after the previous one finishes.
  • Tasks from different pools do not hold each other up: while a domain selection is being computed, link checks and domain history tasks keep running as usual.
  • How many tasks run at once is set by the service administrator — it cannot be changed in your account settings.
  • Different users are processed in parallel and do not affect each other.
  • Progress is visible on the Result page and in the dashboard's "Active tasks" block; you receive notifications when a task starts and finishes.
  • Results appear in the table as they are processed — you can review them without waiting for the task to finish.
There is usually no need to split a list into many small tasks "for speed": within a single task, domains are already processed in parallel (see Parallel processing). In "Domain selection", splitting is outright harmful — such tasks run strictly one at a time and will wait for each other in the queue.
