Hello Christoph,
Because I assume that the improvement realized by this patch will be smaller
than the measurement error I have not yet tried to measure how much this
patch impacts performance. Yet I think this patch is beneficial because it
touches code in the hot path and because it reduces the number of pointer
indirections in that code path.
