## AI overview

This case study describes how Lawmatics optimized its CI pipeline by changing the machine class used for parallel browser end-to-end tests while initially preserving parallelism. The reported result was a 39.3% reduction in average application compute cost per pipeline and a 15.8% reduction in active pipeline duration.

## Source excerpt

CI optimization is easiest to reason about when the problem is concrete: one pipeline, one critical path, and one cost model. Lawmatics reached out to us with that kind of problem. Their application pipeline was already parallelized and already using a sensible CI structure. The remaining question was whether the most expensive part of the [...] The post How Lawmatics Cut CI Compute Cost by 39.3% and Shortened Pipeline Time by 15.8% appeared first on Semaphore.
