The job queue in MediaWiki is a system designed to handle tasks that are too time-consuming or resource-intensive to be performed during a normal web request-response cycle.
The job queue allows MediaWiki to defer tasks that do not need immediate execution. This includes operations like updating link tables when templates change, sending notification emails, re-rendering pages after template edits, or any batch processing tasks.

Cron job
#!/bin/bash
# Put the MediaWiki installation path on the line below
MW_INSTALL_PATH="/home/www/www.mywikisite.example/mediawiki"
RUN_JOBS="$MW_INSTALL_PATH/maintenance/runJobs.php --maxtime=60"
echo Starting job service...
# Wait a minute after the server starts up to give other processes time to get started
sleep 1
echo Started.
while true; do
# Job types that need to be run ASAP no matter how many of them are in the queue
# Those jobs should be very "cheap" to run
php $RUN_JOBS --type="enotifNotify"
# Everything else, limit the number of jobs on each batch
# The --wait parameter will pause the execution here until new jobs are added,
# to avoid running the loop without anything to do
php $RUN_JOBS --wait --maxjobs=20
# Wait some seconds to let the CPU do other things, like handling web requests, etc
