- Date: Monday 15 Feb 2021.
- Hardware: MacBook Pro (16-inch, 2019), 2,6 GHz 6-Core Intel Core i7, 32 GB 2667 MHz DDR4.
- Interpretation: enabling the SemanticDB compiler plugin slows down normal compilation by 45-50%.
- Recommendation: do not enable the SemanticDB compiler plugin during local edit-and-test workflows. The compiler plugin is primarily intended to be enabled in custom CI jobs to upload SCIP indexes.
