# Manual configurations recommended:
#
# 1) General performance and throughput can be increased at scale when you add an
# additional dynflow_executor process This is not managed yet by
# satellite-installer, see: https://bugzilla.redhat.com/show_bug.cgi?id=1692535
#
# Recommended settings:
# 32-64G RAM: 2
# 65G-128G RAM or more: 3
#
# Edit: /etc/sysconfig/dynflowd
# EXECUTORS_COUNT=2
#
# Additionally memory consumption is better controlled when adding the below tuning
# paramter to /etc/sysconfig/dynflowd
# MALLOC_ARENA_MAX=2
#
# These changes require a restart of 'foreman-tasks' service.
#
# 2) Set max open files for httpd. The installer does not yet provide tuning for this
#    see : https://bugzilla.redhat.com/show_bug.cgi?id=1728420

#  mkdir -p  /etc/systemd/system/httpd.service.d/
#  echo "[Service]" >> /etc/systemd/system/httpd.service.d/limits.conf
#  echo "LimitNOFILE=640000" >> /etc/systemd/system/httpd.service.d/limits.conf
#  systemctl daemon-reload
#  foreman-maintain service restart
#
# 3) For conditions that require above a 256 PassengerMaxPoolSize you need to tune
# the kernel:
#
# echo "kernel.sem= 250 256000 32 16384" > /etc/sysctl.d/01-satellite-tune.conf
# echo "fs.aio-max-nr = 1000000" >> /etc/sysctl.d/01-satellite-tune.conf
# sysctl -p /etc/sysctl.d/01-satellite-tune.conf
