The free git Server "gitea" sometimes has problems with the performance of its WebUI. It sometimes takes a few seconds from the click to the reaction in the browser.
To fix this, please try this solution:
The performance problem only seems to occur in HTTP2 (protocol HTTP V2) - therefore apache can be persuaded to use HTTP/1.1:
Add the following line into the SSL part of your apache website config:
... Protocols http/1.1 ...
Finally restart your apache webserver.
