NewReno is a sender-side only algorithm and web-surfing is mostly a
receiver-side experience. If you gather some quantitative numbers
on bulk transfers or a packet trace, I'd be happy to look at them for you.
> Is newreno working as designed right now
Yes, it should work much better than before. There is one outstanding
bug that I now of, which was reported by Lu GuoHan. A patch for it is
in circulation. You can find it at
and see if it affects your web-surfing experience.

Unfortunately, it appears only a few people care about work on
TCP congestion control, even though it affects a lot more users
and is several factors more important for performance than, say, SMP.
