> All text responses (non-javabin) are currently serialized through
> {{QueryResponseWriterUtil.NonFlushingStream}}. The minimal method override in
> that class means that every byte written on all text responses is iterated
> and copied byte-for-byte.
> It is trivial to extend {{FilterOutputStream}} and override the bulk write
> methods, eliminating this potential bottleneck. This came on my radar while
> doing [general investigation into response serialization
> slowness|https://github.com/apache/solr/pull/1440#issuecomment-1462597683]. I
> haven't bothered to benchmark this, but it's a trivial change and could only
> be a good thing, in terms of performance.
