On a large website, after using feedme to import some content it immediatelly triggers the "Updating element slugs and URIs" process that takes very long time to complete. Is there a way to postpone or temporary disable this task and do the import first?
You can try disabling Craft's queue temporarily by adding
'runQueueAutomatically' => false to general.php, then trigger the feed via the command line.
Without testing this might prevent the 'Updating element slugs and URIs' job, but in any case – doing it this way you should see better performance overall.
p.s. if you add
--verbose to the end of the command you can see what it's doing.
