   Got it, it sounds like you already adjusted my set-up to include warm-ups. Overall it looks like a positive performance improvement. I'm in favor of merging this even though the improvement is relatively small -- I think it's good to implement the actual algorithm that we claim to! I also think this sets us up well for future performance improvements, by closely comparing to other HNSW implementations.
   
   One last thing to check regarding performance: does it have an impact on indexing speed?
   
   Reviewing the code with fresh eyes, I found some more parts where I had questions. I know 9.0 feature freeze is coming up really soon, maybe we want to discuss the timing of this PR?
