We're running a v13.0.198 .NET core 8.0 site hosted in Azure App Service. We have been attempting to optimize the site for performance as we found activity tracking was very taxing with the number of visitors we were getting. One thing we noticed is when a user visits the site, they get assigned a new Contact GUID, however, whenever they visit a new page, another Contact GUID is created and assigned to the user.
This is creating 10k+ new contacts per day. So we turned activity tracking off for the time being until we can resolve the issue. At one point the site was crashing every few days because of the number of activities being written at the same time as new contacts being created.
What would cause a single user who visits the site for the first time or has visited the site several times in the last month to have a new contact created for them on every single page load?
