"I can tell you right off the bat probably what's the problem"
Emphasis added. I don't disagree with you that they may be doing something inefficient; I'm just saying, I don't -know- what they're doing, so I'm disinclined to judge it.
I do know that, again, in Rust, whatever bottleneck they're hitting is neither CPU nor memory, despite the seemingly low throughput, which does imply that what you're proposing isn't the bottleneck in that implementation.
