My speedtest result is normal for the connection I have:

I also noticed that loading Kamaddan takes a very long time, while other places load immediatly, in Kamaddan the game usually doesn't go past the loading screen. I noticed the computer isn't doing anything though. CPU usage for GW is at 0% and memory usage only at around 50k MB.
I'll provide any info needed, I just want to have this problem fixed.
Edit; it will probably also load very slow in other big cities, I haven't been able to test it yet. Usually the loading screen stays at 100% in Kamaddan, and after a few mins it loads. It's impossible to run around though, too much lag.
