A performance benchmark of the R language. Many of the subtests are single-threaded, but also note a few multi-threaded points.
Topdown profile looks lightly scatters, reflecting both multiple tests and short duration.
AMD metrics show some floating point, some branches and a somewhat balanced profile between retiring, front end backend and speculation.
