## Highlights
> Supports ramp-up phases and flexible load
> Plugins available to be able to configure flexible load
> Resources Consumption Heavy to run tests with multiple users on a single machine, more memory consumption Lightweight and doesn’t take up so much memory of your machine
> Easy to use with Version Control Systems No Yes
> Add listeners, but consume more memory
> Jmeter is most used when: You need to perform a complex load including different protocols You can record scenarios Robust support and training ecosystem Require that a full scenario be written for every test If you need to simulate specific load with some custom ramp-up patterns If you just prefer UI desktop app for scripts creation, or you just do not know Javascript/YAML/JSON well enough K6 solves some specific problems: CLI tool with developer-friendly APIs. You can use HAR files to generate record sessions Checks and Thresholds – for goal-oriented, automation-friendly load testing Open source, great support and documentation Lightweight uses Javascript Does not run in NodeJS and doesn’t run in a browser
