No, it needs to work in the worst case.  If some script kiddie can peg my
CPU with a synflood then there's still a problem.

Lets work on defining "real world". Factor in the script kiddie.

"real world" is the worst-case DOS tool available.  Synflood tools like
juno seem to fit that category.  If you think juno is not a good
real-world test, then keep pissing people off and you'll find out how real
it is. ;-)

I have spent many hours investigating peoples problems sshing to their
machines only to find out they didnt follow instructions. After the
10th person doing the same thing, what do you expect my reaction to be?

Take 15 minutes and write a web page with the magic settings required to
make things work.

I have many times. I still do. It is also a thankless task.

URL?  I've looked at almost everything on your web page since you were
involved in the pppoe client software.  I haven't seen anything that says
how to sprinkle the pixie dust so my router works well.

No, as I said I'm moving ~30mbps and ~10kpps in and out of 2 3c905cx
cards.

Change your NICs. I dont know what else to suggest.

Yup.  It just takes a bit of time and planning when the box is deployed in
a POP 400km away...

The last time I looked at the zebra list things seemed pretty dead.  Most
of the new work is now happening on the commercial zebra development.

Maybe its time to fork Zebra into something that has the same momentum it
had in the earlier days.

Hmmm... maybe we can both bug MCR to try your suggested changes...

You don't seem to get it.  There's at least a dozen things more important
to me than seeing Linux routing performance compete with Cisco and BSD.

Again, if you wanna complain about it at the level you are i think its
only fair you help. I actually dont care about CISCO or BSD. We dont win
because someone else looses. We simply want to be the best.

You can want to be the best, but I don't think it's fair to sucker people
into using Linux as a core router with false claims.

Now that people like Rob and Dave are taking a hard look at it I think
it's worth my while to ante up for a couple more rounds.  I still fell
like a sucker that should have walked away from the table a long time ago
though.

I think your setup maybe the question. Like i said theres probably a
hunderd variables involved. It is up to you to isolate things.
Yes, theres a support line in open source, but it is rewarded more
when people show some effort.

Fuck, if you think I haven't put any effort into it already then there's
no point in even trying any more.

to be comfortable with what they know best. Most of the people i have
met that put Linux down or consider it a joke come from the old
BSD camp. Its their loss and i dismiss anything they have to say.

In my case I would have been better off to dismiss your advice a year ago.
How does that help the Linux cause?
