Description Chuck Schweizer 2013-10-22 12:41:17 UTC

Description of problem:

A non admin user takes a very long time to load the Dashboard page if they have many nodes. In this instance there were 18,700 nodes returned. The following is the query most/all of the time is spent on. Possibly this should be a join or something more efficient than an IN list.

Version-Release number of selected component (if applicable):

Validated it still exists on foreman 1.3

How reproducible:
easily reproducible if you have a large number of nodes.

Steps to Reproduce:
1.  Add a large number of nodes to foreman/satellite
2.  login as a non admin user
3.  go to the foreman dashboard

Actual results:
Page take a very long time to load.

Expected results:
Page should load in a few seconds.

Additional info:

This is the specific query

Fixed in 83b2874539b2b5469586a23b1edacbdf2a88d2ef in develop.

Comment 6 Dominic Cleal 2014-05-22 18:28:27 UTC

Chuck's reported that Foreman's introduced a regression and it's slowed down again.  It appears that the move to the new authorisation system's caused it as the method concerned has been split into a step to pull back all of the host IDs and then another to look up reports.  It needs dev work again to see if this can be optimised.
