Understanding how to optimize a CI/CD pipeline can dramatically enhance efficiency, reducing a 45-minute process down to just 10 minutes by addressing key bottlenecks.
Common culprits for slow CI/CD pipelines include inefficient scripts, redundant processes, limited resources, and non-parallelized tasks. Addressing these can lead to significant improvements.
Parallelization is essential—by executing tasks like test suites and builds concurrently, I was able to optimize pipeline processes and greatly reduce run times.
Implementing caching for dependencies further reduced pipeline time. In GitHub Actions, using the cache action for npm significantly improved speed and efficiency.
