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 http://people.freebsd.org/~hsu/tmp/explicitnewreno.diff and see if it affects your web-surfing experience. > and if not, who is fixing it ? 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. > Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 > phk@FreeBSD.ORG | TCP/IP since RFC 956
