Set file limit to unlimited to ensure there is no OS problems with files at concurrency:
ulimit -n 9999

Line 106 ⟶ 121:
*To generate significant load it is almost always necessary to run it in distributed mode.
*Master server do not simulate any user itself.
*For this we have to start one or more slaves using –slave flag
*Both the master and each slave machine, must have a copy of the locust test scripts when running Locust distributed.
*Run below command on each slave nodes as well
ulimit -n 9999
locust --host=http://somedomain.io --master
Then start any “slave” nodes, giving them a reference to the master node:
locust --host=http://somedomain.io --slave --master-host=192.168.10.100
== Without WebUI ==
Runs the cli mode as below:
locust -f locustfile.py --no-web -c 1000 -r 100 --run-time 1h30m
In Distributed mode it will wait until all slave nodes have connected before starting the test:
locust -f locustfile.py --no-web -c 1000 -r 100 --run-time 1h30m --expect-slaves
