> I didnt' see a big impact on recall beyond what is typical from noise -- even with the same graph settings we see variance in recall due to randomness in the graph creation when there are multiple threads. I had 'numMergeWorker': (12,), 'numMergeThread': (4,) so that could be the explanation for the variance? Yeah, that could explain variance. For repeatable tests, I generally only merge with one thread, but this is because I am usually doing things that effect recall. But that force merge time difference is 🤯 `143.48` vs `271.95` is HUGE. It seems strange that we would get an almost 2x improvement just from faster vint reading? -- This is an automated message from the Apache Git Service.
