Four very quick points:
- Enabling flowtable can help provided you don't have a large (greater
than a few thousand) number of peers.
- I have a patch under review to cache the rtentry (L3) and llentry
(L2) in the inpcb for TCP connections, which improves scaling at high
packet rates.

Some LAN card chip for fxp is known to cause problem at

The reasoning behind moving the delay in to shared code is not very compelling.

Interesting. That might explain a problem that Mike Silbersack is
seeing with the latest em driver on vmware.
I don't know of any NICs that actually choke on such frames.
Nonetheless, it is silly behavior. I'll try to see if we can get this
fixed before 7.2.

"No buffer space available" is ENOBUFS. This error is returned when
the ifq is full - see IFQ_ENQUEUE in if_var.h. You'll almost certainly
want to set ifq_len to larger than the default for a 10 gigabit
driver. This most likely to be a combination of ifq_len being too

Hi Sean,
Thanks for the prompt response. Are you run
Native ATM relies on the use of route cloning for managing virtual
circuits. Support for route cloning will be removed from the kernel in
the near future. I thus need to determine how many users of NATM there
are and their availability for testing changes.

Calling arpresolve on an rtentry looked up by rtalloc_mpath_fib won't
work because a gratuitous clone route is created without llinfo
attached. As far as I can tell, routes should only ever be cloned for
initial host route creation during a resolve to store arp information.

It is simply a knob to adjust on all new server network cards. You
could benefit from it on a predominantly UDP workload. I believe that
tcp_input is still sufficiently serialized that it would not make
sense for TCP workloads.

However, there is no need for them to know about other socket

Interesting -
Randall - does SCTP depend on ipv6? Or did you mean to have a pipe
between inet and inet6?
netinet/sctp_asconf.c optional inet inet6 sctp
netinet/sctp_auth.c optional inet inet6 sctp
netinet/sctp_bsd_addr.c optional inet inet6 sctp
netinet/sctp_crc32.
Do I need to define additional flags in my config file?
No, unless sctp_pcb.c was somehow removed from your sys/conf/files you
probably need to 'make cleandepend; make depend'. It builds fine for
me with those options.

Hi Jack -
I believe I've fixed the sun4v breakage caused by the interrupt filter
changes but it appears that em still isn't working. Does Intel test at
all on big endian hardware? If not, what do you do to avoid breaking
e1000 on Linux?
Thanks.

One more thing to remember is to raise the socket size on the linux
sender. I found that I got very poor tx performance on linux running
netperf without making the socket buffers fairy large.

This is not terribly surprising rx is currently a more expensive
operation than tx on FreeBSD. My testing on 10GigE indicates that
there is ample room for improvement.

The reason the drivers drop their locks is
that the network stack frequently holds locks over calls to driver output
routines. As a result, driver locks tend to follow network stack locks in the
lock order--at least, for drivers that have a single lock covering both send
and receive paths (quite

It really varies with workload. For a small number of streams I get
much better throughput with it enabled for a 10GigE link.

On a sidenote - my laptop runing 6.1 has a tendency to overheat. I'm
installing RELENG_6 on a desktop for different reasons.

What size are you seeing that is larger? Even if an mbuf chain comes

Evidently FreeBSD violates the LSO spec by sending down up to socket
buffer sized TSO segments to the network card. Is there a way to set
this other than reducing net.inet.tcp.sendbuf_max to a compliant value
