Since all heavy-lifting tasks, like evented I/O and coroutines, are delegated to gevent, you can hack Locust and add specific functionality. It can be installed using the following command: python -m pip install locustio. Locust uses fewer resources to simulate thousands or millions of concurrent users while performing load testing and this is another advantage of this framework. Locust is an easy to use, scriptable and scalable performance testing tool. To install the latest version of the package you would run the following command: pip3 install scrapy Using port forwarding you should be able to connect to the web ui on Locust master node. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle. The poles on the root locus plot are denoted by x and the zeros are denoted by o. One common function used by developers is to make a POST request with curl, which is what we’re going to cover here.

The root locus plot depicts the trajectories of closed-loop poles when the feedback-gain k varies from 0 to infinity.rlocus adaptively selects a set of positive gains k to produce a smooth plot. wrk2. In a browser we call the server where locust is running on port 8089 . Locust.io is very hackable. When more devices are added, it may be necessary to increase the number of Locust workers. To use locust first you need to install it with this command sudo -H pip3 install locust To use locust we must first create a file called locustfile.py , this file describes the tests we want to run using python code, this is an example of the file: Now you can run the locust at command line (in the folder containing the locustfile.py): $ locust --host=host-of-your-app. To create a performance test, ...
