Plugins » Foreman Remote Execution

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1600920

Description of problem:
When trying to run an Insights plan with 1 rule for "Kernel vulnerable to local privilege escalation via DCCP module (CVE-2017-6074)" on nearly 6K hosts, the execution of the plan seems to be very slow.

While this plan is executing, there are no other kind of jobs that are running in parallel(Repo sync, client reg, etc.)

Currently, the job seems to have executed on only 300 hosts in an hour and taking a look at the database, it seems the planning for task is very slow. Only 301 tasks have been planned.

SELECT COUNT FROM foreman_tasks_tasks WHERE parent_task_id='0f814ce4-2a8e-4be6-83a5-4359bcbb98eb';
-[ RECORD 1 ]
count | 301

Not sure, if this issue should go under which component, so marking it for tasks plugin. Please do correct it if necessary.

Version-Release number of selected component (if applicable):
Satellite 6.4 Snap 10

How reproducible:
Always

Steps to Reproduce:
1. Create a insights plan with applicability to about 6K hosts.
2. Execute the plan by clicking on Run Playbook.

Actual results:
The planning of the tasks for execution plan appears to be slow and the tasks seem to run very slowly(nearly serialized - If there are 2 tasks A and B, then B will start only after A has finished).
