I will try to test ipfw and dummynet with netmap in my netork. But there is still a problem with NAT and libalias. I havent tried new SMP-friendly pf NAT, maybe it will give a good perfomance. But it will be also great to have something working with ipfw. I think in my previous list I forget to note about two more problems: 1. Not full support of LACP in FreeBSD (for example it's not possible to set priority, hash algorithm and mode(active/passive)). 2. No support of *RFC 3069 (IP unnumbered/SuperVLAN).* 2014/1/14 Luigi Rizzo > > > > On Tue, Jan 14, 2014 at 6:26 AM, Luigi Rizzo wrote: > >> On Tue, Jan 14, 2014 at 5:48 AM, Vitalii Duk wrote: >> >>> Hello, colleagues! >>> >>> I'm working in ISP and use FreeBSD on BRAS'es. >>> I have noticed that there are few problems in FreeBSD, which do not allow >>> to use it on high speeds (>10G, >2Mpps). >>> >> >> for this type of applications you really want to look at netmap >> >> http://info.iet.unipi.it/~luigi/netmap/ >> >> which already does a lot of what you need. >> > > and if you feel like funding some specific work in this area > you can contact me off list > > cheers > luigi > >> >> cheers >> luigi >> >>> So I have a suggestion to create a list of improvements that needed to be >>> done in FreeBSD collectively, to improve network perfomance and be on the >>> same or higher level as Linux or Vyatta. >>> After we create a todo list, it's possible to organize a donation for >>> those >>> developers who can do that job. >>> I'm ready to donate money for this project, and I think that I'm not only >>> one interested in it.
