Re: sysctl tuning for maximum network performance
because this server also handle spamd/squid/ftp-proxy... I4ve forgotten to mention that.. I4ve got a book (Absolute BSD - The ultimate guide to FreeBSD) I know this isn4t a openbsd book.. but I4ve got some information about NMBCLUSTER and tcp.sendspace/recvspace that might help Sorry for the inconvenient 2005/9/1, Adam <[EMAIL PROTECTED]>: > Diego Augusto Dalmolin <[EMAIL PROTECTED]> wrote: > > It handles the size of listen() queue... > > If you know that, then why would you think it needs to be increased to > do routing and NAT? > > Adam > -- Diego Augusto Dalmolin (41) 9648-0882

Re: sysctl tuning for maximum network performance
It handles the size of listen() queue... I know openbsd is a great SO.. IMHO the best one I ever worked whit!! and I also know Theo & CO. are doing their best to maintain this system I just want to learn.. and I thought misc@ would be a place where I could find relevant information.. my 10 question was: "Where I can find material for studding" sorry if I4m not as good as you I4m just trying to understand how it works -- Diego Augusto Dalmolin (41) 9648-0882 2005/9/1, Ted Unangst <[EMAIL PROTECTED]>: > On Wed, 31 Aug 2005, Diego Augusto Dalmolin wrote: > > > Ok but... don4t you the default values like kern.somaxconn=128 > > are too small for an OBSD router/nat with 2 x Gig lans + 2 x 4Mbps > > internet conections > > do you even know what kern.somaxconn does? > > > -- > And that's why we need each other.

That said, here's what we use on an Internet tap for a site with 1200Mbps aggregate connectivity. net.inet.tcp.recvspace=65535 net.inet.tcp.sendspace=65535 net.inet.ip.maxqueue=2048 kern.somaxconn=2048 net.bpf.bufsize=2097152 net.bpf.maxbufsize=4194304 Note that we've tuned net/bpf.h after testing for the past couple years. However, when/if we would ever need support, we would immediately revert back to GENERIC without the above sysctl's tuned so high. People need to understand that GENERIC doesn't work for everyone, but this isn't Linux. If you're asking how to tune it, the chances are that you do not know enough to tune it. Let GENERIC work for you (it worked fine for us just until quite recently when we added some more bpf hogging applications that were ultra-paranoid about packet loss, etc).

Well, simple, DON'T compile your own kernel. Because those few KB's won't slow your system that much that's it's worth all the hassle you can get from compiling your own kernel.
