  go run --healthCheckPeriod=20

Run the below steps to run the load balancer

1. start the three web servers as follows:

       python3 -m http.server 8080 --directory server-1
   

        python3 -m http.server 8081 --directory server-2
   

        python3 -m http.server 8082 --directory server-3
   

2.    cd load-balancer
      go run .
   

3. Run curl://localhost:8000 or if you want to make concurrent requests run

      curl --parallel --parallel-immediate --parallel-max 3 --config urls.txt
