- Build: Memory footprint
Background: 8 GB is our recommended minimum for building on Windows. New
contributors don't necessarily have high-end developer machines. By
noticing bumps we can evaluate the cost/benefit of these and protract
further bumps of the recommended minimum.
- Tests: Memory footprint during or at end of selected tests
To detect changes in memory allocation. We run the tests anyway.
