           Summary: dmd compile times increased by 10-20%
           Product: D
           Version: unspecified
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression

I see this across all projects that I tested with dmd-2.066.0-rc1.
The compile times went up by 10-20% for debug builds when compared with
dmd-2.065.0. Maybe we can identify some major causes for this.
