we have Sharepoint 2016 on premise and I did a backup of our most important site collection to duplicate it into a test-site. So far so good, the restore worked and the test-site is accessable. My problem: the test-site is very slow compared with our live-site. They are running on the same Farm with the same SQL-Servers (Content is in different tables) and the same user-settings. So what could be the problem? thanks!
