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.

GNU Parallel, where have you been all my life?
> This runs a benchmark for 30 seconds, using 2 threads, keeping 100 HTTP connections open, and a constant throughput of 2000 requests per second (total, across all connections combined).
Some distros include `ab`[2] which is also good, but wrk2 improves on it (and on wrk version 1) in multiple ways, so that's what I use myself.

Ask HN: What do you use to stress test your web application?
I've had my eyes on wrk2 [1]

But I am curious, what does HN use? Any tips?

Running a Billion Workflows a month with Netflix Conductor
We used wrk2, a fantastic tool to generate stable load on the server. Wrk2 improves on wrk and adds the ability to generate sustained load at a specific rate (-R parameter).

How does one answer performance related questions such as these for a web API?
I use tools like vegeta and wrk2 to answer those questions.

Your load generator is probably lying to you
Needs (2015).
I loved the talks from Gil Tene.
I always reach for his fork of wrk whenever I need to test throughput:

what is faster the template engine tera or PHP. is there any template engines for rust faster than PHP
That's why a lot of people just use something like wrk or wrk2 (highly recommended to run it on a separate machine) and benchmark the ability to serve actual requests.

PHP preload VS running as a daemon (benchmarks)
To get the most out of preload, I preloaded all files that the experimental endpoint needs to include. As a benchmarking tool, I use wrk2 — a more advanced Apache Benchmark analog — to keep it simple and provide more flexibility to generate loads similar to a real-life one.

Ask HN: Do you load test your applications? If so, how?
i use https://github.com/giltene/wrk2 pretty regularly.
it has decent lua hooks to customize behavior but i use it in the dumbest way possible to hammer a server at a fixed rate with the same payload over and over.
i run it by hand after a big change to the server to make sure nothing obviously regressed. i used to run it nightly in a jenkins job but 99% of the time no one looked at results. it was nice to see if assumptions on load a single node could handle didn't hold anymore.

3 Benchmarking/load testing tools for different use cases
I use wrk2 because it overcomes coordinated omission.

Implementation of Cluster -Node.js
cluster - npm link loadtest - npm link "os" is a nodejs core module
- Node.js package loadtest can now send 12 krps on a lowly i5 processor

[HELP] Why single thread server runs faster than multi-thread ?
More details: I am learning about node.js clustering. I have 6 core AMD CPU. for testing the load I used loadtest package. Both tests where executed by node server.js

Optimize Node.js performance with clustering
For benchmarking, I will use apache bench. We can also use loadtest which has similar functionality.
To load test our Node.js servers with and without clustering, we will use the Vegeta load testing tool. Other options can be the loadtest npm package or the Apache benchmark tool as well. I find Vegeta easier to install and use because it is a Go binary, and the precompiled executables are seamless to install and get started.

How to push ten thousand requests for load testing?
I used https://www.npmjs.com/package/loadtest but my computer does not go over 100 rps. Why is that? I have a pretty good gaming computer.
What are some alternatives?
