Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Load Testing with Ruby-JMeter
Here comes the ruby-jmeter! An easy to use tool that helps you to write readable test plans, which leads to focusing on your simulator scenarios to become closer to real customer behaviours. Under the hood, it uses JMeter. The code below simulates 10 customers keep visiting Google while its being run.

Load Testing: An Unorthodox Guide
JMeter is old and crusty and not at all friendly to work with. But I used it for years because it was really about the best we had. Today I don't wish it on anyone.
Ruby JMeter finally made JMeter easier to manage, but I haven't worked in a Ruby shop for years, and I'm not going to force everyone to learn Ruby just to do some load testing.

Then along came k6. It's developer-friendly and I've seen people actually enjoy using it. I recommend anyone considering JMeter also take a look at k6. They do a better job of selling it than I do:

I am also Gatling-curious. Seems like an option for anyone in the JVM ecosystem.

Must-have gems for mature Rails
gem "test-prof" - https://github.com/test-prof/test-prof | Toolkit for inspecting and optimising your test-suite, a must-have.

Measuring load time on fixtures
You might be able to do something with https://test-prof.evilmartians.io, but I'm not sure it has anything specific to fixtures out of the box. Maybe using the event profiler on sql.active_record events would be close enough. In the limit, you could wire together your own ActiveSupport::Notifications.instrument around the relevant blocks + an ActiveSupport::Notifications.subscribe to that event so as to log the relevant information.

How to optimize factory creation.
To have a better vision of what objects are created in our spec file we can use test-prof, a powerful gem that provides a collection of different tools to analyse your test suite performance. One of this tool is really useful to identify a factory cascade, let’s introduce factory profiler.

A Trick For Reading Flamegraphs
TestProf can be used to get flamegraphs for Ruby test suites.

Does pytest break a lot of coding rules?
Rspec has spec_helper.rb.

Learning resources to broaden the knowledge
I also love the test-prof documentation, there's a lot of good ideas on how to improve test performance.
