Currently, label size caching uses a System.Tuple as the cache key with
mono's default IEqualityComparer implementation, which seems to add
noticeable overhead. I originally came across this in a flamegraph generated over an interval of 466 seconds on an 86 pawn colony on 1.2:
Using the analyzer on a 1.3 autotest colony with 35 pawns appears to confirm:
Replacing System.Tuple with a custom struct type and handwritten IEqualityComparer appears to yield a small performance improvement of approx. 0.2ms per update:
