Önder ALTINTAŞ,
Thank you for the hints, none of the solutions worked for me still same
performance. Can you test it please with my WFS url at your end..
as a temporary solution, setting the minResolution & maxResolution this
is working for me so far:
var serverVector = new ol.layer.Vector({
source: vectorSource,
minResolution: 0,
maxResolution: 4,
style: vectorStyle
});
