At my current job, the full build/test/release cycle is about 45 minutes. There is an effort to begin optimizing it but it is a high risk endeavor that only became worth it once the costs started growing faster than our team size and became unsustainable.

CI tech debt is very difficult to pay down, and imho not worth it unless the dollar costs are becoming excessive and you have a dedicated release or DevOps engineer who can own it as an internal product.
