[Soekris] net4801 ppp throughput?

2008-10-29 Thread Malcolm Herbert 
I'm using a net4801 running OpenBSD 4.0 for a PPPoE link rather than
my ADSL2+ modem. I am now using the modem in bridge mode as the port
forwarding code in the firmware is rather lacking in features and I'm
quite familiar with pf under OpenBSD as I've used it elsewhere ...

When using the modem as the PPPoE originator my line appeared to support
around 150KB/s sustained, however now that I am using the 4801 for PPPoE
this has dropped to at best 30KB/s, but sustained of around 22KB/s

I can't see that this could be limited by the hardware as ppp consumes
only around 3% of CPU time. The pppoe process appears to be consuming
less than 1% ... the host also does mail, squid and antivirus duties ...

Oddly, when I run ppp with the interactive shell I find that there is a
mention of the connection speed as being 115200B/s, even though in my
configuration the speed has been set to 'async' ... as far as I know
this is the appropriate setting for using ppp with the pppoe process ...

What sort of throughput do others see in this configuration?

Not sure if this is relevant, but I've got a Sangoma S518 (ADSL) card in 
a net4801 with 4640 kbps downlink speed and 512 kbps up. This is the raw 
bandwidth, within which I'm establishing a PPP session using pppd. The 
box is able to saturate this.

The traffic also gets NATted, firewalled and routed by the box.

HTH, Jan
