If you run multiple agents all connected to the same location then they will share the work. A single agent can not run multiple tests concurrently but any number of agents can connect to a single location (I’ve had as many as 12,000 agents processing work at one time).
i am running auto start agents and scale factor set to 10 .when i run 40 test 4 ec2 instances are spun up but i still see only one test running on one instances .
Also agents connected show just one
