While I was at it, I implemented also the improvement mentioned in the third bullet of #23964 (comment). |

Your benchmark job has completed - possible performance regressions were detected. A full report can be found here. cc @ararslan |
This is by factoring out some computations, which is made easier by the `Sampler` framework.
For generating few characters from a string `str`, it's more efficient to use `Sampler(rng, str, Val(1))` rather than with `Val(Inf)`. This change improves this use case, e.g.: sp = Sampler(rng, str, Val(1); C = (rand(rng, sp), rand(rng, sp), rand(rng, sp))

Samplerframework.This should (more than) compensate for the small performance regressions observed in #23964.
