Timing of lights

Coming up Easton Lane to join M3 southbound, the lights actually on the roundabout only let about 3 cars through at a time - this was yesterday 23rd August. With cars coming from A34 and blocking the roundabout by ignoring the Yellow Box, it is very difficult to actually navigate the roundabout. Lots of beeping of horns and aggravation. Took 4 goes to get through those lights. With Macdonalds arriving at Tesco, this might get even worse. Please can you look at sequencing but also consider how to prevent A34 traffic blocking the roundabout as they try to go south. It is the lights just past the A34 exit that was the issue
