1. I just downloaded the latest Julia 1.9.2 and it’s 4x/5x faster than before.
2. If I make the grid above finer I can still make it arbitrarily slow
3. The [linked discussion](https://discourse.julialang.org/t/how-to-plot-10-billion-datapoint-time-series-efficiently/81228/42) is very helpful, but it would be great if there were some easy default options for automated subsampling
