Each row times one of DynamicPPL's reference models on this PR's head. Dim is the parameter count; Linked is true when parameters have been mapped to unconstrained space. t(logdensity) is the wall-clock time for one log-density evaluation. The AD (automatic differentiation) backend columns express gradient time as a multiple of t(logdensity) — a value of 10 means computing the gradient takes 10× as long as the log-density. Lower is better throughout; err means the backend errored on that model. Compare against main below to spot regressions.
