You will have a lot of influence on the project road map and will work with a high degree of autonomy, building and maintaining the tool.

Your responsibilities will be to both write code, extending the functionality of k6, and to maintain the code base, interface with the user community (i.e. review patches :) and potentially evangelize the tool. Your main, long-term goal will be to create the best possible tool and to get as many people as possible to use it.

That's an interesting talk.

k6 allows the user to choose[1] which metrics are relevant for the particular test. By default, it displays max or p(100), p(95), p(90), min, med, and avg. User can specify other values such as p(99.995)

It's also possible to create completely custom metrics[2] to track whatever is relevant to the user.

k6 allows the user to change almost all aspects of execution, tracking, and reporting.

[2] https://k6.io/docs/using-k6/metrics

For that local test, I relied on the k6 CLI output. Influxdb would most likely not be able to handle this amount of data. We are looking to add a TimescaleDB output to enable metric collection beyond what Influx is capable of. There's a working example here if you want to give it a shot ahead of the official release https://github.com/loadimpact/open-source-load-testing-stack

Local execution with cloud output is also possible (k6 run -o cloud), but that's not free.

To give you some idea of what k6 cloud can do, here are screenshots of a few large scale tests https://imgur.com/a/NtXsc1a

1. 500 000 VU test run with 1.5B requests

2. 12h soak test run with 5k VUs

3. 48h soak test, with 5k VUs

4. 20k VU local test (with -o cloud)

The soon to be released "xk6 - k6 extensions"[1] will bring support for many new protocols. There are already proof of concept extensions for Redis, ZeroMQ, kafka, SQL, and others.

Adding MQTT should be rather straightforward.

The most I started on a single machine was about 50.000 VUs. Back then, the limit was in available sockets. k6 now has support for multiple source IPs, so that limit has been effectively removed, and more VUs should be possible.

On the `k6 cloud` side, we have executed 500k+ VUs. The most RPS I achieved with k6 was 4 791 928 (~4.8 million requests per second). That test lasted for 6 min and generated 1.5 billion requests in total.

More is possible, but we didn't push further.

k6 can be used together with Grafana[1] so you can get pretty charts for free :-)

You can give a shot to the "open source load testing stack"[1] we built. It's using TimescaleDB instead of influx which makes it much easier to configure in Grafana.

We are planning on using TimescaleDB as a default database output for the local execution.

Hey all,

Pawel here - one of the engineers behind k6. For the past 9 months we have been working very hard on this load testing platform and today it's finally out! Hope you give it a try!

I'm happy to answer any questions you may have :-)

Please... I just want to get my work done. Let me disable the WYSIWYG :rage:

This is exactly why I'm done with consumer router devices. Open Source routers are mature and infinitely more secure. https://teklager.se/en/open-source-routers/

Load Impact | Go Engineer / k6 OSS maintainer | REMOTE in Europe +/- 3h from Sweden

You will be one of three lead developers and maintainers of k6, a modern open source tool for performance testing, written in Go (golang). k6 was released publicly in early 2017 and has already received over 5,000 stars on Github and has an active community of users and contributors.

Your main, long-term goal will be to create the best possible tool and to get as many people as possible to use it.

Due to our small teams and fast development pace, you will have a substantial and immediate impact on how the end product is architected, developed, and how the engineering team operates. Most importantly, you will work with competent colleagues and will be able to expand your knowledge and skills in different directions.

Load Impact | https://loadimpact.com/ | Python/Backend Software Engineer | Stockholm, Sweden | FULLTIME | ONSITE or REMOTE

Load Impact is the world’s most widely used online load testing service, with over 100,000 users from 190+ countries and over a million executed load tests - Google “web load test"!

We are a small company but very experienced in developing applications for performance testing and monitoring. We started out as a software development consulting company way back in 2000, developing performance test and measurement software for customers such as Nasdaq and the European space agency. We wrote both hardcore, low-level networking software and high-level web user interfaces and became quite good at both of those things. We pride ourselves on understanding the lower levels of a networked application while at the same time realizing how incredibly important UX is. In 2009 we took the step and launched loadimpact.com, becoming a product company rather than a consulting company, and we have never looked back.

Recruiting is ongoing. We will respond to your application immediately. If you don’t have a CV ready, don’t create one, send us a link to your Github/LinkedIn with a few sentences about yourself.
