How can i Improve the load Time of Webtop5

If you have the chance to access the same application from another place/connection that may tell us something.

I have tried accessing it from multiple different connections and still the same happens. I am not really sure why.
What is the average speed of the internet you are using.
Mine is 25 MBPS

Is JRE already running on client before login?

Can anyone here please try to access the same test login from other parts of the world?
It was fast from Italy - FTTC 100Mb - Windows 10 - Chrome.

Loading time form Italy, 100Mb/s: Chrome: ~10s, FF: ~12s
Loading our internal instance from LAN: Chrome: ~ 5s, FF: ~7s

So Nitram, Iā€™d say your instance is running at the same speed as our internal one.
