I have migrated from gogs to gitea, since that migration every time that any user makes a login, its takes too much time, several seconds, to open the next page, after login its seens to work normaly.
In the app.ini file, under the [server] section, I had to change “LANDING_PAGE” to “organizations”. What I observed was that the default page that shows heat commit map on top and all of the histories, was the cause.
By changing the default landing page to organizations, everyone can now log in immediately.
