Load Testing Django Cache Module

[antonpirker]

We have an update for our Django Integration to generate spans that will show up in the "Cache Module" of the Sentry Performance tab.

I did some load testing, to get a feel how much overhead we are putting on our Users Servers.

The project used for load testing can be found here:
https://github.com/antonpirker/testing-sentry/tree/main/test-django-cache-module
(In the /reports folder are the results of my test)

About the memory consumption:

0. This is the baseline, running the load test without Sentry:
   

1. This is the test with Sentry but without any cache spans:
   

2. This is the test with Sentry and with cache spans but without cache item sizes:
   

3. This is hte test with Sentry, with cache spans, and with cache item sizes:

Test case 1 (with Sentry but without cache spans) has a way higher memory usage than test cases 2 and 3!?

I repeated the test case 1 twice and it showed basically the same result (Can be found in the /reports).
