SharePoint Server 2019 includes a feature called fast site creation. Fast site creation allows the provisioning of new sites in a matter of seconds. Fast site creation is only enabled with the following templates, where POLICY# is the identity of the site template being used:
- A OneDrive personal site SPSPERS#10
- A team site (modern only) STS#3
- A communication site SITEPAGEPUBLISHING#0
Fast site creation is activated when using the following provisioning mechanisms:
- OneDrive personal site auto-provisioning
- The Create Site button in SharePoint Home
- Using the -CreateFromSiteMaster parameter with the New-SPSite PowerShell command
There is nothing to do to further enable fast site creation—you just need to use the correct SharePoint site templates and provisioning methods.
