| while we're not racecar drivers, we do depend on high end machines to help us |
| cross the finish line of releasing software. CI and Build systems have bubbles to the |
| top of the list of ASF Infra offerings of interest. most if not all of the projects here use |
| a build system of some sort. |
| |
| Gradle and ASF Infra have partnered to ensure that you're getting the most out of what |
| we're able to offer. |

| I understand that many of you already know these terms, but just in case I'd like to ensure |
| that we're all reading from the same dictionary. so I'm going to define a few things |
| |
| build-time refers to the time a build spends occupying build resources. |
| * 1 build day is 24 hours of non-stop work for a worker node. |
| * whether it's 1 24 hour build or 24 1 hour builds doesn't matter. it's 24 hours of build-time. |
| |
| Flaky tests are tests that _may_ pass on a second (or third) run. |

| == The Need for Speed. |

| Right now, We're seeing an average savings of 12 minutes per build. which admittedly doesn't |
| sound like a lot on its face but that's 81 days worth of build time over the course of the last |
| 10K builds. |
| |
| Build caching alone is responsible for 61 of those 81 days saved. |
| Gradle's Build caching is lowering precious build time spent generating or regenerating |
| build artifacts. |
| |
| I feel this is made even more incredible because we don't even have the full roster of projects |
| using Gradle. As we onboard more projects we expect to see even more time savings. |
| |
| Local and Remote build caching enables savings of an average of over 13 minutes per build. |
| or 90-100 build-days per calendar week. |

| |
| == Better resource utilization. |
| [%step] |
| * Build time avoidance savings correlate directly to build queue times. |
| * Efficient Ephemeral Node usage. |
| |
| All of this to say: builds are getting done faster, sooner. |
| |
| == How do I use this? |
