Omg,  this one is still going on?

Please stop filling those Internet tubes with useless attempts to argument
with a troll. You'd never win. And this whole topic...  Waste of time...

more than 16 dma segs

[Peter Hunčár]

Hello

I'm using a ProLiant G3 as a router for quite a long without any issues.
(4.8-current snapshot, difficult to get this machine out of production)
Unfortunately for last few days I'm expecting strange behavior, (difficult
to describe, but this does not matter now)
I'm getting large amount of interrupts that weren't there before (from 23
to 77 %)
and I found a strange message in dmesg (and during boot, that I did not
notice before)

more than 16 dma segs

Could you please provide me a hint where to look?

Dmesg follows:

Re: network bandwith with em(4)

[Peter Hunčár]

Hello

I have couple of old ProLiants with bxp/em interfaces with 4.8 stable.
If you provide me more info what to test extactly and what output to send,
I'd gladly help.

  Are you suggesting that because you have a quad-port gig nic, your box

reference,
  the net4801 does about 3kpps with 4.9)

 are you sure? that seems low, the 4501 used to do 4kpps with openbsd 3.3
!

 Quite sure, though I certainly welcome someone else doing independent
 testing to prove me wrong. (FWIW: I tested 3.3 last month and got a
 maximum of 2400pps before packet loss exceeded 1%)

 The numbers above are for IP forwarding (not bridging), no PF, TCP syn
 packets with random ports, ISN, and source address, but fixed
 destination address. Measurements are on either side of the device
 using SNMP on the switch, and they match very closely what I'm seeing
 from the endpoints on either side of the firewall. The results are also
 stable across the more than 30,000 individual tests I've run to date
 against a variety of hardware and versions (automated, of course!)

 Note that If you measure on the box itself (i.e. the IPKTS/OPKTS) you
 will get lies when the system is livelocking. If you push harder you can
 get more packets through the soekris but it's meaningless as most of the
 packets are being dropped and the box is completely livelocked.
