Additional Requirements

For the Dashboard server:
  • Connection limit: Increase the open file limit of the operating system if limited by host
  • Request handling: Disable aborting request processing if users close the site (ignore_user_abort in php.ini)
  • PHP functions: Ensure all required PHP functions are enabled

​
Scaling for Network Size

As you add more child sites, your Dashboard server needs additional resources.
Network SizeHosting TypeRecommendations
Up to 30 sitesShared hostingStandard shared plans work well
31-100 sitesReseller hostingAdditional server memory; enable “Optimize for Large Networks” in MainWP Settings
100+ sitesVPSAt least 512MB PHP and WP memory; enable “Optimize for Large Networks” in MainWP Settings
The “Optimize for Large Networks” setting adjusts how MainWP loads data to reduce memory usage. Find it in MainWP > Settings > Advanced Settings.

​
Checking Your Configuration

You can verify your server meets requirements from within MainWP:
  1. Go to MainWP > Info > Server
  2. Review the displayed PHP and server settings
  3. Check for any warnings or recommendations
