--------------------------------------------
{quote}So – we should fix that last issue and see if we can measure the impact
of this change, and then maybe we can find a way to control this per-task?

+1 – could you open upstream ({{luceneutil}}) issue for this?
> Faster advance on Vector Values
> -------------------------------
>
> Key: LUCENE-9674
> URL: https://issues.apache.org/jira/browse/LUCENE-9674
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/codecs
> Affects Versions: master (9.0)
> Environment:
> Reporter: Anand Kotriwal
> Priority: Major
> Time Spent: 4h
> Remaining Estimate: 0h
>
> The advance() function in the class Lucene90VectorReader does a linear search
> for the target document.
> To make it faster we can do a binary search over the "ordToDoc" array which
> will make the advance operation take logarithmic time to search.This will
> make retrieving vectors for a sparse set of documents efficient.
