The performance of your tools, and especially your IDE, has a significant impact on your development experience. For a long time, performance was a pain point for Kotlin developers, especially those who worked with large codebases or with complex code structures. This is why for the past year we’ve been focusing on improving this experience for you. Our goal is to make sure working with our tools is as smooth as possible. We’ve already done a lot of work on that front, but we’re not going to stop here!

If you have ever experienced the blight of a slow IDE, or if you get a kick out of software performance, you’ll like what we’ve prepared for you below. We’ll cover:

• How we measure performance to see where issues are and what to improve.
• How we’ve improved IntelliJ IDEA performance for Kotlin development.
• Our plans for the future.

Our recent versions have fixed a lot of performance issues. If you’ve been reluctant to upgrade because of concerns about breaking changes, we think you’ll be excited by the improvements we’ve made.
