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.
