(CC's reduced, context added, Dmitry Fleytman added for vmxnet3 thoughts).
Then I'm really confused as to what this would look like. A zero copy
sendmsg? We should be able to implement that today.
On the receive side, what can we do better than readv? If we need to
return to userspace to tell the guest that we've got a new packet, we
don't win on latency. We might reduce syscall overhead with a
multi-dimensional readv to read multiple packets at once?
Confused,
Rusty.

smbd's using up 100% of all cpu's and load avg slowly going up
Hi,
I'm having problems in a second domain controller machine. Every time a
restart samba, few time after a samba process starts using almost 100% cpu.
It's a Centos 6.5 x86_64 with the following:
sernet-samba-libsmbclient0-4.1.6-7.el6.x86_64
sernet-samba-ad-4.1.6-7.el6.x86_64
sernet-build-key-1.1-4.noarch
sernet-samba-libs-4.1.6-7.el6.x86_64
