Sorry, something went wrong.
Use precalculated set objects in more places. This is similar to #19385. Some cases were still unoptimized. I used trace logging (#19457) to identify functions where we were creating many set objects, and I noticed that these were unncessary. This is a part of a set of micro-optimizations that improve self check performance by ~5.5%.
