Hi
I have read http://people.freebsd.org/~ken/zero_copy/
To correctly use zero copy receive, it seems it need to set the MTU to:
have to be at least page sized, and be aligned on page boundaries.
So is the default MTU for ethernet network card 1500 works?
Thank you in advance.
Patrick

just an update, with a newer -current it still hangs exactly in the same place,
and on two very different hosts!

Hello,
I'm trying to write a little program which retrieve the value 'sysctl

to a var the value stored in that sysctl using sysctl C call?

I've found my 5.2-RELEASE system hardlocking when I put some decent load on
its bfe interface. It'll do 80% load for hours before it freezes, but if I
do a ping -f it locks up within seconds. I had no problems using this
interface with the Windows driver provided by Broadcom.

Yes.

Correct me if I am wrong:
To use the zero copy 'receive' on i386, you need to set the MTU to 4096 bytes(page
size) or 4096 multiples.
If it is true, until zero copy receive can do auto fitting, I think zero copy receive
is more useful in gigabit ethernet than in fast ethernet (I assume MTU 1500
Just a quick update -- since the individual directories imported ok I decided
to give it a go with the newest (and possibly last before 1.0) subversion,
0.37.0. This time I'm importing the entire src/ repo to see what it can
handle. I'm not quite brave enough to go after ports yet :)

No, just larger than a page-size plus headers. FreeBSD's tcp
automagically sets the mss to a page-sized multiple for large MTUs

I missed the original thread here, so this point may have already been
made ... but ... we tried to use subversion for a proj

That was with a heavily modified version of FreeBSD, you wouldn't be able
to hit 1.6 million out
