| Description |
|
Long ago we downgraded from -O3 to -O2, because we did not observe a performance degradation while doing so, but did observe a compile time improvement. We should re-evaluate this decision given that we are using much newer tools. Such an evaluation must include measurement of the compile time impact. |

Looked like there was no measurable perf increase |
