[AdminRadar] Took 91.092ms to cache 2814/54220 entities

Maybe it's because AdminRadar?

 

Have you tried disabling admin radar to see? Also i have noticed that the restart will hang sometimes at this part and takes around 2-3 minutes extra to load the server. however if i close server wait 30 seconds and then start it can start alot quicker. Does the server stop loading at this stage or does it just take a while?
