The new grid takes ~5.5 seconds, which is roughly 4x more than with the 128^3 grid, as expected. Hopefully this will have more stable performance 😅 |

The 128^3 grid is very small, it finishes running the whole timestepping loop in about a second, and very small glitches during the benchmarks cause frequent false positive performance alerts. By using a slightly larger grid, hopefully we'll have more stable numbers.
