Report Server portal loading extremely slow

I noticed that the loading speed of the RS portal ( the initial loading after logged in) became extremely slow after upgraded the report server from 14.0.* to 15.0.2.402 version, tested using Chrome,...

I have the same issue. The average time to render the portal and its one folder is 40 seconds - Same API as posted.

If I navigate to the Web Service URL, the page loads immediately, however our clients prefer the interface.

Some details: Using Kerberos for authentication. SQL 2017 Backend on a seperate server. Verified all SPNs are valid and working. PowerBI Jan2019 v15

I am hoping someone found a solution, but forgot to post it. :)

(possible solution)

Hi all,

We experienced the same performance problems as described here. Loading portal pages took more than 30-40 secs, there were no CPU or SQL issues. Our on-prem Power BI Report Server (v. Jan 2019) is used by our co-workers in various locations/offices and behind a Amazon Route 53 DNS using a specific hostname. Then I got pointed in the right direction by using developer tools in Chrome returning some 401 http errors in the network tab.
It turned out all I had to do is add the hostname we are using to the registry of the Power BI RS and reboot the server. Please check the following kb article, for us Method 1 solved our problems.

  Hello,
  
  I have the same problem. Power BI Report Server + SQL Server the same machine... and every call to api/v2.0/me is extremally slow (about 14s).
  
  Did you find a solution?
