I did something recently to compare my MapServer performance with local mounted 
storage for geotiffs and S3 geotiffs. I ended up building a Python script using 
Locust:

https://locust.io/

I ended up putting something together that worked for what I wanted and could 
scale to different numbers of fake users and be deployed across my Kubernetes 
cluster. Bottom line for your original question is to use the `requests` 
library to make a URL request from within Python. The locust python library 
gives you access to the `requests` library to do that, but with all of the load 
testing stuff you may want to do in the long run.

The overall suggestions from all the responses you've gotten so far are more 
important to consider though: don't just get a response time for a single 
request, but for many requests. Don't just do the same request over and over 
again, make it semi-random to avoid reporting the results of internal caching 
in MapServer.

Hello,

I want to measure how long does it takes for my WMS to response to GetMap 
request. I have prepared list of extents in form of python list for example:
['38.04778703973034,-17.714089101743628,39.04778703973034,-16.714089101743628', 
'38.04778703973034,-17.714089101743628,39.04778703973034,-16.714089101743628'...]

I'm aiming into itterating over this list and passing it's elements into GetMap 
request inside python script and then request GetMap and measure how long does 
it takes to perfome it.

Here starts my question: How to do GetMap request inside python script, is it 
possible? The question is not about creating the url but about function wich 
does request.
Maybe somebody can recommend me some other way of measuring speed of WMS?

I would like show my k8s cluster service as use-case at FOSS4G 2023 and i need 
some statistics for presentation 🙂

Best,
Marcin
