Speaking of lateral thinking in optimizations, I'm curious as to both why electric network updates do have such a heavy memory bandwidth impact, and whether that impact could be avoided in the common case.

This is not about programming, this is about CPU and memory hardware. To be able to ...

I love the FFFs in general, but amongst the various FFF subjects, my favourite is optimisation. I love to see how thinking things differently can lead to overall improvements, and also the failed attempts, where a seemingly obvious amelioration leads to worse performance because the bottleneck was ...
