For (b) consider that the reason why small articles can't keep up may be
history lookup issues, and more streams MAY help, while for large
articles bandwidth is usually the problem. You can gain a little by
switching to compressed batches, but if the content is the usual jpeg or
mp3 it doesn't compress well and you rarely get enough improvement to
solve the problem.
For feeding small text articles, compressed batches are still very
effective at overcoming network bandwidth issues, since 2-3x reduction
in bytes is usually possible.
