Hi,
I tried upgrading to lucene 8.5.1 from 8.4 and ran our internal
benchmarking. We noticed that with this upgrade our QPS dropped more than
40% and also affected latencies. After doing some profiling and reverting
LUCENE-9211 <https://issues.apache.org/jira/browse/LUCENE-9211> commit
related to BinaryDocValues compression, we recovered ~30% of the loss. Did
anyone encounter similar situation?

We rely on BinaryDocValues very heavily. Should this newly introduced
compression be optional to opt-in?

Also, any other pointers for on recovering remaining 10% loss. When I run
benchmark on 8.4 index with 8.5.1 code, performance is very similar to 8.4.

Thanks,
Viral Gandhi
