Well, I’ve literally observed it (circa 2016 and design has not significantly changed with this in that time) and confirmed my finding with percona. deadlock was the wrong terminology to use, apologies, I keep writing from my phone as I am travelling at the moment: I meant lock contention, specifically in memory. A deadlock would be a hard stop but what I observed was a bottleneck on memory bandwidth past a certain number of cores (24) with update heavy workloads. So, appreciate your points but I don't think I am wrong in the core thesis of my statements. x :)
