Hello, There's no easy answer to this apart from Don't display 500 feature at the same time.
There's a couple of tricks for that: - If it's points, use the cluster startegy. - Only display the vector from a scale where they will be useful. Use WMS before that point. - Preprocess your data to have less geometry when zoomed out Others may have some advice as well.
