Okay, I have something both confusing and concerning to report: a major speed decrease in at least some rules between v4.972 and v4.98. Specifically, for b35s2467/C1, v4.972 averaged about 55000-60000 soups/sec/core and and about 81.9 tiles/soup. However, with v4.98, the speed nearly
halves to 30000 soups/sec/core with around 226 tiles/soup.
However, for another rule, b2cei3aekqr4aijkny5cky6-ai78s02ai3jknq4jtyz5-acjy6-an7e/C1, there is a speed
increase from around 1200-1300 soups/sec/core to 1600-1700 soups/sec/core, with the tile rate going from around 3800 tiles/soup to 2100 tiles/soup (there is a lot more variation with this rule compared to b35s2467/C1).
As a third reference point, b2k3acijr4ijqy6i7cs2aek3ijnqr4it5n/C1 goes from ~240000 tiles/soup... to around ~240000 tiles/soup, so that appears to be unaffected.
As a fourth reference point, b3-ekqr4nt5r6is02-c3/C1 goes from 4800-4900 soups/sec/core and ~490 tiles/soup to around 3800-3900 soups/sec/core and ~660 tiles/soup, another major
slowdown.
Is a correction of one part in 2^18 really expected to cause such huge changes, or is something else going on here?
