Robert Muir commented on LUCENE-10125:
--------------------------------------
I agree, but don't think it needs to be {{tryWriteLong}}. It can be named
{{writeLong}}. We should just add a ctor check to OutputStreamIndexOutput
requiring that buffer size is at least 8. This way we never have to fall back
to super().
E.g. if the buffer is 1K, and it has 1021 bytes in it already, we should just
call flush() to force it to be emptied a bit earlier. and always write longs
with VH.

> There's been a significant drop in indexing throughput between 2021-04-12 and
> 2021-05-24 on the NYC Taxis benchmark. Unfortunately several suspects have
> been merged during that period of time so we might need to git bisect to
> figure out which one is responsible for the regression. Interestingly the
> sorted index looks less affected than the non-sorted indexes.
