Anyone seen this before?

Odd, I wonder if the 6x test is using up CPU in the router (might not be optimal at PPPoE for the high speeds of FTTP)

Yes I think you're right. I've also got a Fortinet 30D to try which is rated to 800Mb on simple traffic, 350mb on IPSec so should be able to handle the throughput of this line. I'm going to get hold of Draytek first to see if they want to do any debugging on this first (although I suspect they'll say that router isn't designed to do 300Mb PPPoE).

Last time I emailed Draytek, they said their router couldn't cope with any more than 50Mbps over the WAN. Have you considered using a software router like pfSense running on a high spec PC?

Really? For a 2860? Interesting..

The exercise is more to find an 'affordable' easy to manage device that can cope at this speed. pfsense will 100% do it, but it doesn't really fit into the highly repeatable simple device model that an ISP like the one I work for would be interested in. So far, I've only had reliable results from devices costing >£350 (like the fortinet 30d)..

Sorry, no - it was an earlier Draytek device.

Even the Asus RT-N66U has been reported to struggle with FTTP 330/30 - http://forums.smallnetbuilder.com/showthread.php?t=9425

Have you tried to telnet to your router and run top when doing the speed test to see what the resource usage is like?

Version 3.0.0.4.374.2050 of the Asus firmware (you can find it here under Drivers and Tools) has the comment:

5. Fixed PPPoE throughput issues.

It's probably in the Merlin code too, but can't say what it does as I don't have speeds where it would matter

Are you sure it is the router and not the PC?

Mr S will be the best to answer it but surely the PC is initiating 6 separate downloads and the router does not really care what the traffic is on the single network connection - it delvers traffic packets ass addressed/translated.

Would this be an option? http://www.cisco.com/en/US/products/ps11997/index.html

It has only recently been released but is certainly sub £300 (online prices are around £135) and it looks like it has the specs to cope with 330.

While they are all HTTP (TCP port 80 based) this will mean six entries in the NAT to handle things. So yes will be a greater load as the router handles the on going routing.

So yes PC is doing six downloads, but router is handling six streams of traffic.
