Two things for histograms: when fetching for the buckets, lookup (and therefore only copy) the bucket config instead of the entire record). Second, keep buckets as a big tuple instead of a big list, which is smaller and therefore cheaper to copy, and also can apply binary search during the bucket lookup instead of linear search over a list.
Also for gauges, improve their performance and fix a bug about setting a gauge to undefined for integer or floats.
