[keycloak-user] Keycloak freezes for more than 40 seconds after checking state cookie

Hi all, We are using Keycloak 3.4.3 on Windows 10. We are using user created in Keycloak database. But after providing the login credentials, Keycloak freezes for more than 40 seconds at following points. 2018-05-08 19:11:24.679 DEBUG 15900 --- [0.0-8445-exec-5] o.k.adapters.OAuthRequestAuthenticator : checking state cookie for after code 2018-05-08 19:11:24.679 DEBUG 15900 --- [0.0-8445-exec-5] o.k.adapters.OAuthRequestAuthenticator : ** reseting application state cookie 2018-05-08 19:12:10.775 DEBUG 15900 --- [0.0-8445-exec-5] o.k.adapters.OAuthRequestAuthenticator : Verifying tokens Keycloak and browser both are local. Please advise, what could be the potential cause for this freeze. Also, is there any performance optimization guide for Keycloak. Please guide. Regards, SR
