This mod is still creating server load when "Disabled" under the Main Settings options. I currently have to go into the Product Manager and disable it there to get it to stop.
When disabled in the Main Settings I am still seeing caching and calls to these items:
/e360mods/holiday/hooks/cache_templates.php
/e360mods/holiday/hooks/init_startup.php
/e360mods/holiday/hooks/parse_templates.php
/e360mods/holiday/hooks/process_templates_complete.php
/e360mods/holiday/hooks/template_groups.php
