When running AdminUI, trying to show the configuration an OIDC client or a partnership, it takes around 50 - 70 seconds for the page to be completely loaded in the browser.
AdminUI 12.8SP7 on RedHat 8;
Policy Server 12.8SP7 on RedHat 8;
Policy Store on CA Directory 14.1.04;
Policy Server and AdminUI run on the same machine;
Upgrade the Policy Server and the AdminUI to 12.8SP8 to benefit from fix DE576551.
