Cuprajake There was some optimisation work going on this morning….and extract below of what I just read this morning.
It seems that as FreeFlarum gained popularity, the current server and hardware setup is not enough to keep up with all the forums. I have attempted to fix this issue by reducing the amount of online forums by clearing some inactive ones. However, many people have requested their forum to be reactivated, which rendered this step technically useless. As more and more forums appear, the activity is higher and higher, and there are less inactive forums to be removed.
Unfortunately, I did not have the time to look into this in more detail to find the exact cause because of my exams. But I should have some time next weekend. I will do some research in order to optimize it better. Expect a downtime next Saturday morning while I tweak some server configurations in order to counter this
