# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
email@fellipe.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.

- [Apache JMeter](http://jmeter.apache.org/download_jmeter.cgi) - Open source load testing tool: It is a Java platform application.
- [Locust](http://locust.io) - An open source load testing tool. Define user behaviour with Python code, and swarm your system with millions of simultaneous users.
- [Autoperf](https://github.com/igrigorik/autoperf) - Autoperf is a ruby driver for httperf, designed to help you automate load and performance testing of any web application - for a single end point, or through log replay.
- [HTTPerf.rb](https://github.com/jmervine/httperfrb) - Simple Ruby interface for httperf, written in Ruby.
- [PHP-httperf](https://github.com/jmervine/php-httperf) - PHP Port of HTTPerf.rb.

- [k6](https://k6.io/) - An open source load testing tool built for developers. Easy to integrate into CI pipelines. Tests are written in ES6 JS and you can test APIs, microservices and sites using HTTP/1.1, HTTP/2 and WebSocket.
## Web server Modules
- [PageSpeed Module](https://developers.google.com/speed/pagespeed/module/download) - PageSpeed speeds up your site and reduces page load time. This open-source web server module automatically applies web performance best practices to pages and associated assets (CSS, JavaScript, images) without requiring that you modify your existing content or workflow. PageSpeed is available as a module for Apache 2.x and Nginx 1.x.
- [WebP-detect](https://github.com/igrigorik/webp-detect) - WebP with Accept negotiation.
# Specs
- [Web Performance Working Group](http://www.w3.org/2010/webperf/) - The mission of the Web Performance Working Group, part of the Rich Web Client Activity, is to provide methods to measure aspects of application performance of user agent features and APIs.
- [Page Visibility](http://www.w3.org/TR/page-visibility/) - This specification defines a means for site developers to programmatically determine the current visibility state of the page in order to develop power and CPU efficient web applications.
- [Navigation Timing](https://w3c.github.io/navigation-timing/) - This specification defines a unified interface to store and retrieve high resolution performance metric data related to the navigation of a document.
- [Resource Timing](http://www.w3.org/TR/resource-timing/) - This specification defines an interface for web applications to access the complete timing information for resources in a document.
- [User Timing](http://www.w3.org/TR/user-timing/) - This specification defines an interface to help web developers measure the performance of their applications by giving them access to high precision timestamps.
- [Performance Timeline](http://www.w3.org/TR/performance-timeline/) - This specification defines a unified interface to store and retrieve performance metric data. This specification does not cover individual performance metric interfaces.
- [CSS will-change](https://drafts.csswg.org/css-will-change/) - This specification defines the `will-change` CSS property which allows an author to declare ahead-of-time what properties are likely to change in the future, so the UA can set up the appropriate optimizations some time before they’re needed. This way, when the actual change happens, the page updates in a snappy manner.
- [Resource Hints](http://www.w3.org/TR/resource-hints/) - This specification defines the dns-prefetch, preconnect, prefetch, and prerender relationships of the HTML Link Element (<link>). These primitives enable the developer, and the server generating or delivering the resources, to assist the user agent in the decision process of which origins it should connect to, and which resources it should fetch and preprocess to improve page performance.
# Stats
- [HTTP Archive](http://httparchive.org/index.php) - It's a permanent repository of web performance information such as size of pages, failed requests, and technologies utilized. This performance information allows us to see trends in how the Web is built and provides a common data set from which to conduct web performance research.
# Other Awesome Lists
- [iamakulov/awesome-webpack-perf](https://github.com/iamakulov/awesome-webpack-perf) - A curated list of webpack tools for web performance
- [bayandin/awesome-awesomeness](https://github.com/bayandin/awesome-awesomeness).
