bq. Can you recommend a way to benchmark this myself, like if I wanted to tweak 
it to see how my ideas work out?

bq. ... There are a few more things I've identified that can be improved here, 
around the defaults, ...

I don't know what the ideas or things might be but just wanted to share that 
Lucene has {{MAX_DOCS_PER_SLICE}} and {{MAX_SEGMENTS_PER_SLICE}} constants and 
slicing logic -- 
https://github.com/apache/lucene/blob/releases/lucene/9.9.2/lucene/core/src/java/org/apache/lucene/search/IndexSearcher.java#L325-L332
 -- and I'm planning to run some experiments w.r.t. reducing the 
{{MAX_SEGMENTS_PER_SLICE}} to 1.

(And to be clear, I'm not suggesting that {{SolrIndexSearcher}} provide a way 
for users to be able to configure these {{MAX_*_PER_SLICE}} values, just 
sharing that the slicing logic is there.)
