To determine if the network had issues with increasing traffic (or number of Vusers) during the load test, what merging graphs will you use to make this determination? Choose Two.
1.Running Vusers with Transaction Response Time
2.Running Vusers with Hits per Second
3.Running Vusers with Throughout
4.Running Vusers with Transaction Performance Summary


是选2，3还是1，3？请指教，谢谢！
