Re: OpenBSD PPPoE performance test results

Juuso,
Thanks for updating your docs - it does you proud as a researcher that
you evolve your results and build on critism. Nowerdays this is rare.

Unfortunately, can you, in retrospect see the problem with your OpenBSD
figures:

Linux 2.2 ... 100%  pppoe 95%, nc 5%  
Linux 2.2 ... 50%  pppoe 40%, nc 10%  
Linux 2.4 ... 26%  system 24%, nc 11%  
NetBSD 1.6 ... 23%  system 15%, nc 17%  
NetBSD 1.6 ... 23%  system 15%, nc 17%  
FreeBSD 4.7 ... 100%  ppp 80%, nc 15%, interrupt 5%  
OpenBSD 3.2 ... 99%  system 87%, pppoe 65%, ppp 23%, nc 7%  

(I don't recall OpenBSD supporting SMP.... :-)

Hello,

Since I may have unintentionally given a wrong picture of OpenBSD's
PPPoE support in my article published on http://derbian.org/pppoe/ , I
want to clarify things a bit.

First of all, PPPoE on OpenBSD works - it was probably only a
configuration error that caused the problems we faced. I'm sorry for the
any inconvenience or spread of misinformation we might have caused.

Now that I have finished the benchmarking on OpenBSD, I have published
the updated article, which now includes information on OpenBSD's PPPoE
performance.

And what comes to FreeBSD PPPoE support, I will study it a bit more as
soon as I have time. The fact that FreeBSD has in-kernel PPPoE support
wasn't stated in their documentation in any obvious manner. The Handbook
entry about PPPoE doesn't say a word about kernelmode PPPoE.

Since I'm not subscribed to the list, please contact me directly if you
want to provide any feedback.
