I used the contact sheet at the bottom of every page "Contact us". BTW my Firefox browser is configured to clean the cache when closing. This effect of non-loading-threads always comes unpredictably, right now the mentioned windows open here without delay too. But it always happens now and then, windows take five minutes or more to load until you finally stop before getting angry . . . I'm not that much into servers, but maybe you can look up the server history and see what happened when I tried to open that window about ten minutes before I did the posting.
If you configured your browser to empty the cache every time you close it, then it is obvious that you will have in general a worser performance than others.
You will facing longer loading times on reentering a thread, when others using cached information.
This is very noticeable on picture heavy threads.
Load times and virtual observed board performance will be always worser without cached information.
So normally it's not a good idea to clear the browser cache every time you close your browser.
As The Internet protocol (IP)is a connectionless protocol it is always possible to loose packets of a transmission (which has to be fetched again after a timeout).
So the observerved behavior can also be related to the IP packet routing from the FPN server to you.
And there is nothing you or the server hoster can do to to improve such a thing, if your request is routed through a "bad" hop.
It can also be related to your Internet connection if e.g. the signal quality is bad and a lot of transmission errors occur, you can check your router protocol on this.
So there are a lot of possible root causes, which can lead to your observed problem.
At least my observation is, that the board feels very fast now (don't equal picture load times with board performance, as most pictures are hosted externally).
