Param cached update very slowly. #2288

Open Andor233 opened 1 year ago

Andor233 commented 1 year ago 
    def send_param(param, value):
        print(value)

    rospy.impl.paramserver.get_param_server_cache().set_notifier(send_param)
    rospy.get_param_cached("test")

When I set the param "test", the value will be printed with over 1 min delay.
