Hello @zcwbnu

I’m not sure what makes you say that the map refresh rate is 30Hz. There’s no such ‘clocking’ of the redraw. I would first refer to [this answer](https://mapwindow.discourse.group/t/map-operation-is-very-slow-when-disk-cache-files-are-too-large/1043/2) and see if it helps.

Regards,  
Jerry.
