That’s a different problem. I was responding to a comment asking about benchmarks for concurrent reads. In general we have CPU systems with hundreds of cores nowadays, so I think it’s hard to say something is “the problem” as far as parallelism goes. For example, I have a problem where I got a 100x speed up in the “computationally difficult” part of the problem… suddenly all the stuff that looked too cheap to bother with became more noticeable!
