Load testing your WordPress Blog or CMS is made extremely easy by LoadForge. We are going to be showing how to simulate a real set of users, browsing through your latest blog posts at random.
Load testing (aka stress testing) your WordPress Blog or CMS is made extremely easy by LoadForge, and you can test it with a free account today. We are going to be showing how to simulate a real set of users, browsing through your latest blog posts at random.
The first step on LoadForge is adding your Host. We're going to be load testing https://mmo-population.com/blog/ - the Blog for MMO Populations. The first step is going to Hosts on LoadForge and adding "mmo-population.com" as a host and verifying it.
Next up we add our Test. When you head to Tests you will select your Host, and set several key variables:
Then the main part is your locust file. You can run a very simple basic test and just test your index page (e.g. / or /blog). Or, you can use an advanced test like the one we will give you below to crawl the site like a real user.
There are 3 main components of our test description:
Below is your test:
from locust import HttpUser, task, between from pyquery import PyQuery import random class QuickstartUser(HttpUser): wait_time = between(5, 9) def index_page(self): r = self.client.get("/blog/") pq = PyQuery(r.content) link_elements = pq(".blog-list-post h2 a") self.blog_urls =  for l in link_elements: if "href" in l.attrib: self.blog_urls.append(l.attrib["href"]) def on_start(self): self.index_page() @task(1) def static_content(self): # images self.client.get("/img/logo/logo.png") self.client.get("/img/images/cta_img.png") self.client.get("/img/logo/logo.png") self.client.get("/img/images/footer_fire.png") # styles self.client.get("/css/compiled.css") # scripts self.client.get("/js/compiled.js") @task(3) def blog_post(self): url = random.choice(self.blog_urls) r = self.client.get(url) @task(3) def home_page(self): self.client.get("/blog/")
Note: you should replace the static content section with your static urls (or use the wizard to generate them). Also make sure your CSS selector for blog links is correct, and your url (e.g. / vs /blog/)
Now you can start your load test. Once you begin you will see a live status output of the test, like the below:
Once the test completes you will be given a full report on the performance of your blog. You can also run the test again with more users, different settings, etc. We recommend starting with a smaller number of users and scaling up as you see you are not getting failures.
Below are a few sample images of the reports for our test:
Remember that if you use / instead of /blog/ you should change that in the test. You may also need to change the
link_elements = pq(".blog-list-post h2 a") line to match your URLs.
While you are at it, make sure you read our guides on high performance Nginx and PHP-FPM:
Interpreting the results of your test are as important as running the test, if not more. Continue this on our reading load test results guide.
