Chapter 2. Performance Tuning Quickstart

You can tune your Satellite Server based on expected managed host counts and hardware allocation using built in tuning profiles included in Satellite that are available using the installation routine’s tuning flag. For more information, see Tuning Satellite Server with Predefined Profiles in Installing Satellite Server in a Connected Network Environment.

There are four sizes provided based on estimates of the number of managed hosts your Satellite manages. You can find the specific tuning settings for each profile in the configuration files contained in /usr/share/foreman-installer/config/foreman.hiera/tuning/sizes.
