AA speed indicator update frequency weak

After updating ABRP to version 6.1.0 (3491) the speed information refreshes with a delay of 3 to 5 seconds (not sure, I have to drive my car). This should clearly happen more often, once or better twice a second, to have the real speed on display. I use to check the speed when I enter a speed limited stretch of road and want to be sure about the speed displayed being correct.
