How can I troubleshoot performance issues in CircleCI?

I'm experiencing slow builds in CircleCI. What can I do to troubleshoot this?

There are several steps you can take to troubleshoot slow builds in CircleCI. First, check your resource class settings to ensure you're using an appropriate class for your builds.

What are resource classes, and how do they affect build performance?

Resource classes in CircleCI define the amount of CPU and memory allocated to your jobs. Higher resource classes can significantly speed up builds.

How can I monitor the performance of my builds?

You can monitor build performance by using CircleCI's built-in insights and metrics features, which provide detailed reports on build times and resource usage.

Are there any best practices to optimize CircleCI builds?

Yes, some best practices include caching dependencies, using parallelism, and optimizing your Docker images to reduce build times.
